Salt has been around for so long and has a historical significance that predates any culinary ingredient on our shelves today. The History of Salt has intermingled with religion, trade, economics, and geopolitics in surprising ways over the course of history.
One type of salt that stands out for its historical significance and utility more than any other ingredient is kosher salt. This unique form of salt has surged in popularity in recent decades, so wed like to explain its properties, uses, and differences from other types of salt.
Iodized salt is often processed with corn (kitniyot ) and requires Passover certification. Non-iodized salt does not require Passover certification, nor does sea salt. It seem like it may be able to be certified kosher but I would just buy Kosher salt.
Kosher Salt vs. Sea Salt
Both kosher salt and sea salt are hailed as some of the purest and healthiest salts out there. But what characteristics set the two apart?
All salt comes from the sea, whether harvested from seawater or surface mines. The difference between seawater and land mines may lead to a slight variation in mineral content. Sea salt is mainly mined from evaporating or precipitating salt from seawater. Kosher salt, on the other hand, is mostly mined from salt deposits and mines found on land.
Both kosher salt and sea salt are coarse salts, although kosher salt is more coarse with its larger and uneven grains. Sea salt can be as coarse as kosher salt or as fine as table salt, which is dictated by how it is processed.
Both sea salt and kosher salt are some of the least processed salts. However, sea salt is processed even less than kosher salt because it is evaporated from seawater and packaged without additives or refining.
Kosher and sea salt are both very pure forms of salt. With a few exceptions, kosher and sea salt dont have additives like iodine or anti-clumping elements. Although due to concerns about seawater pollution by microplastics such as polyethylene and terephthalate, kosher salt is now considered purer than sea salt.
Kosher salt consists of pure white crystals. This homogeneity in color arises from the fact that most salt deposits on land are white in color. Sea salt can come in a wide variation of colors due to the differences in seawaters color throughout the world.
Kosher salt comes at different price points but generally costs less than sea salt. Sea salt is more expensive due to its purity as the least refined type of salt and the labor-intensive industrial practice of harvesting sea salt.
How Is Kosher Salt Made?
There are two types of kosher salt, the first is the coarse-grained kosher salt that is mined just like any other type of salt, and the other is kosher salt that meets traditional Jewish guidelines. For a kosher salt to be accepted as kosher, it has to be certified by a Jewish institute.
The most popular type of salt extraction is through the solar evaporation of seawater. Most of the salt comes from the sea. Salt, in fact, makes up about 2.5%of seawater. The seawater is then taken through various evaporation ponds where various seawater minerals precipitate at different temperature points. Alternatively, the salt found in the rich salt deposits of the earth, such as kosher salt, can be mined from underground mines. These underground mines are places that were once seas that later evaporated.
The salt is then sorted, separated, and processed to make kosher salt. The third method is the vacuum evaporation method. In this method, vertical wells are dug into a salt mine or deposit. Water is forced down one well as brine is pumped up the other. The brine is then stored in tanks before being taken to vacuum pans. The brine and water temperature are systematically regulated to precipitate varying textures of salt at different temperatures.
Kosher-certified salt, commonly referred to as “kosher salt,” means that the salt has met the guidelines outlined by Jewish law and upheld by kosher certification agencies and members of the Jewish faith. The certification ensures that the product is produced and handled in accordance with these high standards and is suitable for consumption for those following a kosher diet.
Certified kosher salt is mined, just like all other types of salt. The difference is that the mining, processing, and packaging happens under strict Jewish guidelines. This means that no additives or chemical elements are added to the salt that may go against the kosher tradition. Once the salt processing is done, a rabbi or a recognized Jewish institution vets the salt and certifies that it meets cultural requirements.
What’s the Difference Between Kosher Salt, Table Salt, and Sea Salt?
FAQ
Is iodized salt kosher?
What’s the difference between kosher salt and Morton iodized salt?
What are the different types of kosher salt?
Is kosher salt iodized?
Here’s what I found out. Additives: Nearly 70% of table salt in the United States is fortified with iodide, a necessary nutrient that’s been added to salt since the 1920s to help prevent iodine deficiency, according to Global Health Now. The main kosher salt brands sold in the United States like Diamond Crystal and Morton are not iodized.
Does iodized salt taste better than kosher salt?
Iodized salt can leave a slight aftertaste for some users, says Roszkowski, while kosher salt tastes cleaner to some loyalists. Availability: While you can find table salt at even the most poorly stocked grocery store, you might have to hunt around a bit more to find kosher salt.
Is salt kosher?
Many different types of salt available in stores can be certified kosher and bear the certified kosher symbol on their label (iodized table salt, for instance). If you are following a low iodine diet, always verify on the label that the salt does not contain iodine.
Why is sea salt better than kosher salt?
Sea salt contains more naturally-derived nutrients—even more than kosher salt. Iodized salt was created in the early 2oth century to account for a lack of dietary iodine. The contemporary American diet is no longer lacking in iodine and some palates find iodized table salt to have a chemical aftertaste.
