Consequently, in humid climates, it will trap moisture from the air, making a crisp crust soggy, and therefore shortening shelf life. In dry climates, however, the salt helps hold water in the bread longer, inhibiting staling, and thus extending the bread's shelf life. Salt, of course, adds flavor to baked goods. It also potentiates the flavor of other ingredients, including butter and flour. Salt comes in several forms, including fine, course, sea salt and
