Biscuit
In the Southern United States, biscuit means a form of bread similar to a roll made with baking powder or baking soda as a rising agent rather than yeast (rolls made with yeast are often called "yeast rolls" to distinguish them, and biscuits and corn bread are sometimes referred to collectively as "quick bread")A basic biscuit recipe includes flour, shortening (often lard), baking powder or soda, and milk (buttermilk or sweet milk). Common variations involve cheese or sugar.
In Europe, a biscuit is a harder baked product which in North America would be called a "cookie". The origins of the word mean twice cooked.
