Do you know the difference between sea salt, kosher salt, and regular table salt?
Salt is salt, no matter the type. At its core, salt is simply sodium chloride. The chemical composition stays the same whether it’s table salt, sea salt, or Himalayan pink salt.
The differences come from how the salt is processed and its texture. These factors affect flavor, how salt dissolves, and even how it enhances your cooking.
Refined table salt is the most common. It’s heavily processed, with added anti-caking agents. Its fine texture dissolves quickly, making it great for baking. Sea salt, on the other hand, comes from evaporated seawater. It has a coarser texture and a more natural flavor. Some varieties also retain trace minerals, adding subtle differences.
Specialty salts like kosher or flaky Maldon salt stand out for their texture. Kosher salt is less dense and easier to control when seasoning. Flaky salts add a crunch and a pop of flavor when sprinkled on finished dishes.
This post explores the types of salt and why they matter in the kitchen. You’ll learn how processing affects taste and how to choose the right salt for your recipes. By the end, you’ll understand that while salt is salt, its unique qualities can elevate your cooking. Let’s dive in!
Table Salt
Table salt is processed to make it fine, uniform, and easy to use. Manufacturers mine it from underground salt deposits. They refine it to remove impurities and minerals. The salt is then ground into small, even grains. This fine texture allows it to dissolve quickly in liquids.
Producers add anti-caking agents like calcium silicate or sodium ferrocyanide to prevent clumping. These additives keep the salt free-flowing, especially in humid conditions. Some table salt also has iodine added. Iodine helps prevent thyroid problems like goiter. This practice started in the 1920s as a public health measure.
Table salt has a sharper, saltier flavor than less processed salts. Its fine grains make it perfect for baking, where precise measurements and even distribution matter. It also works well for seasoning soups, sauces, and boiling water. However, it’s less ideal for finishing dishes. Its texture and taste lack the complexity of sea or kosher salt.
When cooking, use table salt where it will fully dissolve. Avoid it for rubbing on meats or garnishing. Stick to its strengths, and it will enhance your dishes effectively.
Sea Salt
Sea salt comes from evaporated seawater. Producers collect the salt from saltwater pools then dry it naturally or through heating. This minimal processing helps retain minerals like magnesium, calcium, and potassium. These minerals give sea salt subtle flavors that vary by region.
Sea salt grains are coarser and less uniform than table salt. The texture can range from fine to flaky, depending on how it's processed. Sea salt doesn’t usually contain additives or anti-caking agents unlike table salt. Some varieties have a natural moisture content, giving them a slightly damp feel.
Sea salt’s unique texture and taste make it ideal for finishing dishes. It adds a light crunch and a burst of flavor when sprinkled on top. Use it to garnish roasted vegetables, grilled meats, or desserts like caramel and chocolate. Fine-grain sea salt can also work for seasoning during cooking, but it doesn’t dissolve as quickly as table salt.
Because it is less refined, sea salt has a more natural appearance. It’s popular in recipes where the visual and flavor impact matters. While it’s not essential for every dish, sea salt can elevate simple foods with its distinct taste and texture.
Kosher Salt
Kosher salt is known for its coarse texture and pure, clean taste. It’s made by compacting salt crystals into flat flakes or hollow pyramids. The result is a larger, irregular grain that is easy to handle. Unlike table salt, kosher salt doesn’t usually contain iodine or anti-caking agents, though some brands may include them.
Its name comes from its traditional use in koshering meat. The coarse grains effectively draw out moisture during the koshering process. Today, chefs favor it for its versatility and ease of use.
Kosher salt’s larger grains make it perfect for seasoning. It’s easy to pinch and sprinkle, giving you more control over the amount. It also adheres well to meat and vegetables, making it ideal for rubs and roasting. Because it dissolves slowly, it’s not the best choice for baking or quick-cooking dishes.
When using kosher salt, remember that it’s less dense than table salt. You may need to use more to achieve the same level of saltiness. Always measure carefully, especially when converting recipes. Its mild flavor and practicality make it a kitchen staple for cooking and finishing dishes.
Conversions
1 teaspoon table salt = 1 ½ teaspoons kosher salt
2 teaspoons table salt = 3 teaspoons kosher salt
1 ½ teaspoon kosher salt = 1 teaspoon table salt
2 teaspoon kosher salt = 1 ⅓ teaspoon table salt
Himalayan Pink Salt
Himalayan pink salt is a unique and visually striking type of salt. It comes from ancient salt mines in the Punjab region of Pakistan, near the Himalayas. Unlike other salts, it’s mined as rock salt, not harvested from water. The pink color comes from trace minerals like iron, calcium, magnesium, and potassium. These minerals also give it a subtle, slightly earthy flavor.
Himalayan pink salt is less processed than table salt. It’s often sold in larger crystals or coarse grains, which you can grind as needed. This makes it different from finer, more uniform salts like table or kosher salt. Because it’s minimally processed, it doesn’t include additives or anti-caking agents.
Compared to sea salt, Himalayan pink salt has a denser structure and a milder taste. Its mineral content gives it a slight nutritional edge over other salts, though the difference is small. It’s popular for its aesthetic appeal and is often used as a finishing salt or in salt grinders.
Himalayan pink salt is also versatile. Use it for seasoning, curing, or as a decorative touch. Its coarse grains work well for grilling or roasting, while fine versions dissolve easily in cooking. Additionally, it’s used in salt lamps and spa treatments, though those benefits are largely anecdotal.
Fleur de Sel
Fleur de Sel is a delicate, high-quality sea salt harvested from the surface of salt ponds. It forms naturally in coastal regions, particularly in France.
The process begins when seawater evaporates under the sun, leaving behind salt crystals. Fleur de Sel forms only under specific conditions, usually during warm, windy days.
It’s hand-harvested by workers using wooden tools to collect the crystals before they sink to the bottom. This makes it labor-intensive and rare.
Fleur de Sel has a light, flaky texture that makes sprinkling easy. The crystals are larger than table salt but finer than coarse sea salt. The salt is moist and delicate, with a subtle, sweet flavor due to the minerals in the seawater. It also has a faint briny taste, which adds complexity to dishes.
Chefs love Fleur de Sel because it enhances food without overwhelming it. Its texture and flavor make it perfect for finishing dishes. Sprinkle it on vegetables, meats, or even desserts like chocolate or caramel. Fleur de Sel is a natural garnish that adds crunch and flavor, making it popular in cooking and at the table.
Why Some Salts Taste Different
Some salts taste different because of the minerals they contain. These minerals come from the environment where the salt forms. They don’t change the basic structure of salt, but they add subtle flavors.
For example, Himalayan pink salt contains iron oxide, which gives it a faintly earthy, metallic taste. Sea salt often includes trace amounts of magnesium, calcium, and potassium. These minerals add a slight bitterness or brininess, depending on the source.
Celtic sea salt, harvested from coastal marshes, has a damp texture and higher mineral content. It tastes briny and slightly sweet. Black lava salt, enriched with activated charcoal, has a bold, smoky flavor. It’s often used as a finishing salt for dramatic presentations.
Even salts from similar sources can taste different. For instance, Fleur de Sel from France has a delicate, slightly sweet flavor due to the way it crystallizes in seawater. In contrast, Hawaiian red alaea salt gets its unique, earthy taste from volcanic clay.
These mineral flavors enhance certain dishes. For example, flaky sea salt works well on caramel desserts, while smoky black salt complements grilled meats. The mineral variations give each salt its own character and culinary purpose.
Most Expensive
The most expensive salt is Murray River Salt, harvested from the Murray River in Australia. Murray River Salt flakes are priced at approximately $10 to $15 for a small container (around 8 oz), with larger quantities running higher.
This salt is known for its unique, beautiful pinkish color and large, delicate crystals. It is hand-harvested from ancient, mineral-rich salt deposits in the river, where the salt evaporates naturally. The process is labor-intensive, which contributes to its high price.
The high cost also comes from the salt’s rarity and the specific conditions required for its production. Only a limited amount can be collected annually, adding to its exclusivity. It is often packaged and sold in small quantities to maintain its luxury status.
As for taste, Murray River Salt has a mild, soft, and slightly sweet flavor. The saltiness is not as sharp as that of more common salts, like table salt, making it ideal for finishing dishes. Its smooth, light texture makes it a favorite among chefs, especially for use in gourmet recipes, desserts, or sprinkled on delicate dishes like seafood or salads.
Its rarity, labor-intensive harvesting process, and unique taste contribute to its premium price.

If you are dealing with small amounts, like those mentioned above, then the conversions are okay. But according to the authors of "The New Best Recipe" (the same people who write Cook's Illustrated), there can be a big difference between brands of kosher salt. I know that for Diamond Crystal kosher salt, they gave a conversion ratio of 2:1. That is, use 2 teaspoons of kosher salt if a recipe calls for 1 teaspoon of table salt. For a different brand of kosher salt (I think it was Morton's), they gave a conversion ratio of 1.5:1 -- the same one that you mentioned.
Again, this really won't make a big difference if you are measuring in teaspoons, but if you want to brine something and are using a cup or two of salt, then it can make a difference.
Don't you love how people go nuts over salt grinders? They don't seem to understand that salt is a rock and it's not any fresher if you grind it yourself. Love your site!
The Reluctant Gourmet
Hi iPont,
Great comments about the difference in salts. I am one of those people who enjoy my salt grinder not because I think it is any fresher, it just reduces the size of the salt when I add it to finished dishes. I also like the feel of grinding the salt as I do grinding pepper. – RG
Mike Chauvet
The Prof is correct when it comes to basic table salt v kosher v sea, but there are literally scores, maybe hundreds of gourmet salt varieties. I've never actually used them, but I've seen them in gourmet stores and on Iron Chef. They are amost always colored due to impurities being left in the crystal structure.
Colette
Don't make fun of my Salt Grinder! I love it! I know it doesn't make salt fresher, but it's what every gal needs...a gimmick! 🙂
Colin
Yes, I love the salt grinders for entertainment value. There's a very well known spice brand sold here in Africa that recently added "Freshly Ground Atlantic Sea Salt" to their extensive product range. Now, no weekend meal with friends is complete without the hilarity of a discussion about the need to use such freshly ground salt on our food. Mock tantrums have ensued when one or other guests were forced to use pre ground salt to sprinkle over their plate instead of the freshly ground that their delicate palates favour. What a laugh. I wonder how many people find a 'genuine advantage' in freshly grinding their salt not realising they've being suckered.
David
Actually there is a significant difference in different salts. While it is true that NaCl is a constant, salts contain other chemicals and minerals in addition to NaCl. Sea salt has many minerals and other salts in it, table salt generally has iodine added, kosher salt is generally pure. And when it comes to cooking the way each salt dissolves can be quite important to overall taste of the final dish.
Jennifer
Thank you for this. There is absolutely variation in taste among varieties of salt. Compare David's Kosher to Haddid's Kosher/Sea; the former, soft, flakey and pungent (in a good way); the latter, course and slightly sweet in addition to its pungency; neither contains anti-caking agents to absolutely no detriment, which is probably what allows their natural nuances to shine through. Compare these to the starkness of Morton's Table Salt... Perhaps, it's the additives in regular table salt that make it taste so inferior.
Dennis
The only way you're going to taste the difference in the various salts is to try them right out of the box, or in fairly large quantities an a bland base. Once you put the salt in a food, there is little chance that you will taste the difference. This has been proven in test after test. However, you are correct that the differences in texture affect the blending properties, or the "crunch" appeal in something like a dry rub. Everything else is just snob appeal.
Mike
There's a tremendous difference between certain types of salt and I agree with David...It's true, NaCl is NaCl and it is a constant, but if a taste test was performed most people would agree there's a taste difference in salt. Hey, H2O is H2O but there's a difference in the taste from brand to brand and state to state!
As for the gourmet salts, well, I have to admit, I use them. I notice a difference in taste when using higher quality and smoked salts used for finishing. If use directly in the cooking process there's no diffeence, unless the smoked salts are used.
For the record, I don't consider sea or kosher salt as gourmet. I purchase both at my local supermarket for the purpose of cooking. Finer salts used for finishing which are more pleasing to the palet can be found and bought over the internet.
Great Site!
Dennis
Sorry, Mike, but you are absolutely wrong about the taste tests. Tests have been performed, repeatedly, and people cannot tell the difference between "nasty" table salt and "gourmet" sea salt (or Kosher salt), except in those applications like a rub where the raw salt remains separate from the food.
Diane
I am commenting from a health stand point. I was told not to use salt because I was retaining an excess of water which caused my blood pressure to shoot up. My ankles looked like tennis balls! I stopped using table salt in cooking, on top of foods and little to no eating out. I was told by another Dr. I wasn't getting enough salt and to buy sea salt. I use tons more (sea) salt than before and dropped 10 lbs and no more swelling. My blood pressure is great! I wonder what is in table salt that isn't on the lable? or Why does sea salt work different in the body?
Any answers?
Thanks!
Dennis
The answer to why does sea salt work differently in the body is easy. It doesn't.
Elisa
I would like to know where I can buy Kosher Diamond sea salt. Please help thank you
Crazy Uncle Mark
Actually Mike is correct in that for sea salts the mineral content change the taste dramatically, as well as smoked salt.
More importantly even though the professor is technically correct that NaCl is NaCl, the shape of the crystals, surface area, have a HUGE effect on rate of solubility and chemical reaction with the food - hence why kosher salt is used for rubs and other things - the surface area of the crystals behave differently when marinating, curing, smoking or cooking, so I think the professor was oversimplifying things a good deal, perhaps he did not do enough "lab" work on this one.
Alton Brown did an entire episode on "Good Eats" called "eat this rock" which on Foodnetwork was Episode EASP03 , transcript available here:
((http://www.goodeatsfanpage.com/GEFP/index.htm))
Amazon will ship diamond crystal kosher salt.
Good luck and happy cooking!
Travis
I just happened by this article in looking for unrefined salts. While I obviously protest to the professor's claim that salt is salt, I will bet that he is referring to processed salts. Salts are refined in order cater to the industries that need it to be. Somewhere in the neighborhood of 7% of processed salt goes to the grocery store. More commonly it goes to make bleaches, acids (Hydrochloric and Muratic (meaning brine)), and explosives. Essentially, this process strips salt of 82 of its 84 natural ingredients leaving only sodium and chloride. At this point iodide is added (which is in such a small amount that it does not meet the daily required intake). The myth here is that processed salt is alright for human consumption. Unprocessed salt naturally balances the ph levels in the body. Processed salt is acidic and therefore increases the acidity in the body. Cancer thrives in acidic environments. Is it no wonder that cancer cases are so common these days? After knowing these facts taste is almost an after thought......LOL!
The Reluctant Gourmet
Hi Travis,
Thank you for the additional information about salt. You must be a big fan of one of my favorite authors, Harold McGee. I appreciate your taking the time to explain the science behind salt to me and my readers.
Dennis
Thanks? Really? The "additional information" provided by Travis is pure hogwash. "Processed" table salt is neither acidic nor base; it is about as neutral as you can get. I would challenge Travis to provide a single scientific source for his claim. And as for table salt causing cancer, it is well known that eating too much salt can cause certain kinds of cancer, but this applies to all kinds of salt. Suggesting that unprocessed salt is safe, and that it even helps protect against cancer, is almost criminal.
Dennis Owner
Why are you so triggered over salt. BTW you haven't backed anything you said up either. What do you work for, Big Table Salt or something? Go away please.
G. Stephen Jones
Thank you for your feedback Dennis.
Fitz
Travis,
You did not cite any sources for your post. When I search the internet for references, all I can find are sites trying to sell some unregulated "health" supplement. For example, http://bit.ly/96esUM (Don't miss the section that equates basic ionic chemistry as a "process of attaining higher levels of consciousness" - as if rocks had sentience!) And here are a few fact checks on your post:
You state that NaCl table salt is acidic. False. It is pH neutral - neither acid nor base. There exist acid salts, such as cream of tartar, but the name is a misnomer; some acid salts are actually basic.
Where does this so-called "fact" of "84 natural ingredients" in salt come from? Which salt? Which location? Just because it's "natural" doesn't make it safe. Does it contain chromium? Lead? Mercury? Radium?
Where does this myth that "cancer thrives in acidic environments" come from? There is zero evidence (other than internet rumor) that this is true. See http://bit.ly/9qJpjS
Call me skeptical, but unless it's tested, independently, repeatedly, by different people, and published openly, it's conjecture. When coupled with selling something, it's quackery.
I prefer to treat my body with respect and not cram substances hawked by charlatans.

I found the conversion from Kosher to table salt but can you tell me what a conversion from Kosher to Sea salt would be. My husband bought sea salt and I would like to use it up. Thanks
The Reluctant Gourmet
Hi Carrie, not that much difference. According to Morton salt:
1-1/4 teaspoons of Kosher salt = 1 teaspoon of sea salt
1 tablespoon + 3/4 teaspoon Kosher = 1 tablespoon + 1/4 teaspoon sea salt
Hope this helps, RG
Mr. Bob
Wow, you are an idiot. That is like saying all sauces are the same, except for added ingredients.
Mr. Bob, you're delivery is a bit over the top, but I'm thrilled you have an opinion. - RG
Bill
Hey Mr. Bob? It takes one to know one. Sauces are a bad reference since they can be made from different ingredients. And one person used water taste in different areas as an example. Excuse me but H2O is H2O. All you taste is the minerals and chemicals that it may contain. The professor is correct. NaCl is NaCl in it's pure form.
Matt
Salt is salt. I work in a grocery store and it is funny the fuss that people make about sea salt. It tastes the same as regular salt and there is no difference in nutrition. It is just another fad. The same people who are buying sea salt are the same ones who are buying Greek yogurt right now.
Siacri
I would agree with you(matt) on the salt thing...but Greek Yogurt (the whole milk real cream version is true greek) has an entirely different process of getting to the final product. However,if you want to say "nonfat greek yogurt" then i will agree..technically theres no such product as nonfat greek yogurt..thats almost an oxymoron..by tradition greek yogurt is made from the cream thats ripped from the milk..what they are doing to produce a nonfat immitation of greek yogurt is probably something those who consume it should (but likely dont want to) know! I shudder at the thought...calf hooves?
Nikki
"You may have also heard that sea salts contain more minerals than table salt. Again not true according to Wolke. The process of crystallization actually purifies the salt to its basic elements - NaCl"
I was told by my nutritionist to pick out sea salt that was still off color not white because then it hasn't been purified to remove the minerals. Based on that I'm confused about your statement: if its down to its basic structure, why does my Celtic sea salt have a different color and 330mg of sodium per 1/4 teaspoon vs table salt at 590mg per 1/4 teaspoon. Plus, wouldn't there have to be something else in it beyond the basic chemistry crystal structure Na Cl to change it's color? I doubt they would add dyes but if it's all a marketing gimmick then that would still be a strong possibility, but it wouldn't explain the difference in sodium content on the nutritional label. Please enlighten me! I'm never happy about falling for marketing gimmicks but I know my body reacts different to sea salt vs iodized salt non-iodized salt and kosher salt.
Also the salt grinder I use isn't to make it fresher. It's because I had issues with the already ground Celtic sea salt. It appears to absorb a LOT more moisture than table salt because the salt shaker and bag of salt would stick together much worse than table salt. So, I started buying the less expensive, larger grain salt and grinding it because even if it's stuck together, grinding it still gets it out of the bottle and onto my vegetables. I only mention this because the difference in physical properties between table salt and my Celtic sea salt doesn't add up if it's both NaCl and NaCl only. How do they get away with this?
The Reluctant Gourmet
Not being an expert in salt is why I referred to what I heard Robert L. Wolke say on NPR. I did a quick search and found this interesting article that was posted in the Washington Post on September 6, 2000 that may answer some of your questions. I will say that when you buy any kind of sea salt there is more to it than basic NaCl and that’s why it comes in various colors and has different tastes. I’m not saying that these additional minerals aren’t good for you or add another layer of flavor. I don’t know. I’m not a food scientist. I was just expressing what I heard Mr Wolke say that day.
If you read part 1 from the Wall Street Journal article on salt, I think you will have a better understanding of what sea salt is and what is not. I’ve also provided a link so you can read part 2 and part three of the article. I hope this helps – RG
Robert L. Wolke's Comments on Salt
Please tell me about sea salt. Why are so many chefs and recipes using it these days?
Boy, am I glad you asked that question! I’ve been waiting for a good excuse to vent my spleen on that subject. Stand back.
There is so much nonsense out there about sea salt that it’s hard to know where to begin. It’s easy to dismiss the assertions of some health-food faddists, who often require no evidence whatsoever before adopting a fervent conviction. Among the statements I’ve seen are that sea salt is “unrefined,” “organic,” “more natural,” “more healthful” and “a living food,” whatever that means. (Does it bite back?)
Poppycock, all. ‘Nuff said.
Moving from the ridiculous to the sublime, it’s not quite as easy to dismiss the pronouncements of respected chefs and cookbook authors, whose statements tend to be accepted as gospel even when misguided. Their misguided statements tend to cluster around two supposed virtues of sea salt: its high mineral content (a claim made even more passionately by health-food addicts) and its superior flavor. I’ll address the mineral question in this column and the flavor issue in my next one.
Those magnificent minerals
If you evaporate all the water from a bucket of ocean (fish previously removed), you will be left with a sticky, gray, bitter- tasting sludge that is about 78 percent sodium chloride–salt. Ninety-nine percent of the rest consists of magnesium and calcium compounds. Beyond that, there are at least 75 other elements in very small amounts. That last fact is the basis for the ubiquitous claim that sea salt is “loaded with nutritious minerals.” But cold, hard chemical analysis tells the tale: The minerals, even in this raw, unprocessed stuff, are present in nutritionally negligible quantities. You’d have to eat two tablespoons of it to get the amount of iron, for example, in a single grape.
Bowl of salt sludge, anyone? Not in the United States, because although people in coastal regions of some countries do use this raw material as a condiment, the Food and Drug Administration requires that food-grade salt be at least 97.5 percent pure sodium chloride.
But that’s only the beginning of the Great Mineral Hoax. Because of how food-grade sea salt is extracted, the stuff that winds up in the stores contains about 10 times less mineral matter than the raw salt sludge. Food-grade sea salt is obtained by allowing the sun to
evaporate much of the water, but by no means all of it–and that’s a critical distinction–from shallow ponds of seawater. When the concentration of sodium chloride in the ponds gets to be about nine times what it was in the ocean, it begins to crystallize out, whereupon it is raked or scooped out for subsequent washing, drying and packaging.
The vital point that nobody seems to realize–or admit–is that this “natural” crystallization process is in itself an extremely effective refining step. Sun-induced evaporation and crystallization make the sodium chloride about 10 times purer– freer of other minerals—than it was in the ocean.
Here’s why.
Whenever you have a water solution containing a preponderance of one chemical (in this case sodium chloride) along with a lot of other chemicals in much lesser amounts (in this case the other minerals), then as the water evaporates away, the preponderant chemical will crystallize out in a relatively pure form, leaving all the others behind. It’s a purification process that chemists use all the time. The crystallized salt (called solar salt) that is harvested by solar evaporation of ocean water is therefore about 99 percent pure sodium chloride right off the bat. The other 1 percent consists almost entirely of magnesium and calcium compounds. Virtually all of those other 75-or-so “precious mineral nutrients” are gone. To get that single grape’s worth of iron, you’d have to eat about a quarter of a pound of solar salt!
Even beyond that, some brands of sea salt are the result of subjecting the solar salt to the same further purification steps as mined salt, reducing their mineral content effectively to zero.
Is “sea salt” sea salt?
Let’s not forget that mined salt is also sea salt, because the underground salt deposits were left by ancient seas that dried up. It therefore has a very similar composition–minerals and all–to today’s sea salt. And how about this little-known fact: Your “sea salt” might not even have been taken from the sea, because manufacturers don’t have to specify their sources and according to industry insiders I have talked with, fibbing does occur. Two batches of salt may be taken from the same bin at the mine plant and one of them labeled for sale as “sea salt.” Well, of course it is. It just crystallized a million
years earlier.
Many sea salt enthusiasts deceive themselves by thinking that there are only two kinds of salt: mined salt in the shaker and sea salt in the fancy packages. Not only may the “sea salt” have come from a mine, but on the West Coast the salt in the shaker is most likely to have come from the sea. The point is that a salt’s characteristics depend much more on how the raw material has been processed than on where it came from. You can’t just generalize. There are probably a dozen brands of genuine sea salt with crystals of a variety of sizes, shapes and degrees of purity. Some are straight solar salt, while some have been purified further.
The bottom line is that when a recipe specifies simply “sea salt” it is pure folly, and stems from a lack of knowledge, misguided political correctness or a thoughtless desire to climb onto a popular bandwagon. And you know what? It may make absolutely no difference anyway.
That was a teaser for my next column, in which I’ll examine a few flavor fables. Do sea salts really make food taste better than mined salts? And if so, which ones are best? Don’t go too far away.
The other two columns by Mr Wolke can be found at Sea Salt Shakedown – RG
And about salt grinders, in his third column, Salt, the Final Episode, Mr Wolke says this about salt grinders,
Pounding salt
I can’t end my series of salty remarks without commenting on those classy salt mills and combination salt-and-pepper grinders that are sold in so-called gourmet shops. The idea seems to be that if freshly ground pepper is so much better than the powdered stuff in cans, then why not use freshly ground salt as well?
That’s a (highly profitable) delusion. Unlike pepper, salt contains no volatile, aromatic oils to be released by grinding. Salt is solid sodium chloride through and through, so a small chunk is absolutely identical to a large chunk in everything but size. Other than its
novelty appeal, the only virtue of a salt grinder is that it deposits coarse little chunks, instead of tiny grains, on your food, and the burst of saltiness you get when you crunch them can be fun.
So go ahead and buy one if you wish, but don’t believe the hype about “the superior flavor of freshly ground salt” printed on the cute little card that comes with it.
Brian
What about the supposedly non-edible salts? Morton's website claims that their water-softening salts cannot be used for consumption - is that true? There are many types of salts that are not comprised of Sodium and Chloride, so I don't want to consume something deadly. Yet, I need to find a cheap source of bulk salt for crisis preparation. Can anyone tell me if rock-salt, solar-salt, water-softening salt, etc, can be consumed? thanks, Brian
The Reluctant Gourmet
Great questions Brian and I look forward to some expert responses but I personally would not consume rock salt, solar salt, or water softening salt. – RG
Kerry
I was also wondering about that same thing, Brian. While I called their consumer line and inquired, I was told that there were no additives, but it couldn't be called food-grade because it does not go through the rigorous standards of the edible versions. But I still don't know what the heck the bottom line is on that.
Josh G.
There's an interesting note here with a clearer explanation about surface area. This is certainly more relevant to "finishing" salt than salt getting added to boiling water. I'm not sure if there's a "middle ground" of interest. (I.e. if I add salt to roasting potatoes is it getting fully disolved? What about while frying a green vegetable?)
http://cooking.stackexchange.com/a/8901
Maksim
Sea salt contains some potassium chloride, along with traces of other salts and minerals, which gives it a slightly bitter (and a slight hint of metallic) taste.
Have you noticed that some potato snacks contain potassium chloride, and how that affects the taste? They definitely taste more sea-salty.
Jay
Indeed, some companies may put additives into their salts (i.e. extracting iodine and salt from seaweed and adding the iodine to the salt), but just as many sell natural salts with minerals that have been added from the surrounding earth.
Saying all salt is the same is misleading, take for example the different levels of toxic elements and heavy metals in the analysis (on spexcertiprep.com) linked below. In particular, Potassium, Magnesium, Calcium and Iron levels can all very greatly. Maybe not between common table salt and common kosher/sea salts as much, but more so the varied exotic salts.
The presence of different minerals typically alters the salts color and will most definitely affect its taste.
Relevant: http://www.spexcertiprep.com/knowledge-base/files/AppNote_GourmetSalts.pdf
It's just a shame the analysis didn't go into each salts composition in detail.
The Reluctant Gourmet
Hey Jay, great comments. I didn't mean to say all salt is the same but NaCL=NaCL. Yes, the alternatives do make "exotic" salts different but what percentage of home cooks use these specialty salts? I would guess the majority of us home cooks are common table salt, then kosher, then sea salts. Thanks for sharing the analysis link.
John
So to sum up: Other than the differences, they are all the same.
Hope that thyroid treatment works out for you.
Steve
Very interesting... It does seem that although different kinds of salt definitely taste different in dry form, but once the salt is dissolved into food it does all kind of taste the same!
So I've thought of a good way to test this further. Drink different combinations of saltwater with various kinds of salt (they should all taste the same). I will actually try this sometime - yum!!!
Eric
Can't thank you enough. I was to the point where if I heard another reference to kosher salt I was going to throw the remote at my television. Now I can just laugh and call them idiots in my head.
