Sea Salt and Kosher Salt
Sea salt and kosher salt are both by-products of refining salt. Sea salt is the liquid produced by distilling salt. Kosher salt is salt obtained by extracting the salt from seawater.
Sea salt is primarily used as a seasoning agent for food and beverages. The concentration of sea salt is two parts salt to one part water. The skin of sea plants also contributes to sea salt. Sea salt can be prepared in numerous ways.
Commercial sea salt comes in powder form. The salt can be ground using a mortar and pestle, or it can be pounded to a fine consistency with a hand grinder. The resulting mixture is then frozen and crystallized before it is reconstituted and used in cooking.
Kosher salt is readily available at almost any grocery store. In the United States, salt is a legal item, and kosher salt is certified. Salt, which is derived from seawater, is considered kosher because of its precise set of ratios of both sodium chloride and potassium chloride.
Kosher salt should be prepared as kosher salt. It can be distilled, enriched or precipitated. To make distilled kosher salt, sea salt is first heated in a closed vessel. The resulting vapors escape through a tightly fitted lid. The resulting salt solution is filtered and deionized and then concentrated.
If sea salt is filtered through a cloth before being filtered again, it becomes very rich yellow liquid. After filtering, it is enriched with charcoal or clay. All About Sea Salt is then combined with potassium chloride and sodium bicarbonate to give a finely powdered product. The resulting liquid is then filtered and then deionized.
In general, sea salt and kosher salt are prepared in the same way, but they have different names. There are kosher salt manufacturers who insist on using the word salt interchangeably with kosher salt. If you do not want to purchase kosher salt, use sea salt instead.
