Blessing on Salt
The Bracha on salt, as listed in Mishneh Torah, Blessings 8:8 is Shehakol. I have found confirmation in modern generally accepted Halachic sources.
According to Mishneh Torah, Blessings 8:7 spices normally have no Bracha at all, before or after, as they are not food.
Salt seems to be in the same category. While salt is, in some ways, an essential part of our diet, added salt - and certainly salt eaten by itself - is not normally needed as we get sufficient salt as part of many different types of cooked and baked foods. Salt added to a food right before eating (i.e., can see and taste it) would never get a Bracha of its own as it is Tofel to the item, as with other spices or condiments.
Why does salt, eaten by itself, get a Shehakol?
