Is there a nutritional difference between kosher salt and sea salt?

While there isn’t much of a chemical difference between kosher and sea salts, their origins and tastes do vary. Kosher salt, like the table variety, is mined from the earth, but comes in large crystals with a subtle flavor profile and usually contains no additives. (Table salt undergoes processing, which grinds it into small crystals, removes minerals and adds anti-clumping and anti-caking additives). Sea salt is collected form evaporated seawater, involves very little processing and contains zero additives. Due to the varying mineral content of seawater, the color and taste of sea salt can vary among the regions from which it originates. The major difference between the two salts is use: Opt for kosher when you want a larger grain and sea salt as a direct substitute for table salt.
