Whats the difference between salted and unsalted butter?
Salt acts as a preservative and adds flavor to butter. Lightly salted butter is sometimes called “sweet cream butter,” and is best used as a table butter and for general cooking needs. Unsalted butter, too, is “sweet butter,” but is used mainly for baking. Although unsalted and salted butter may be specifically recommended for cooking or baking particular items, they can generally be substituted for one another.
