Pancakes are thin, flat and often round cakes made from a batter and cooked either on a hot griddle or a frying pan. Most pancakes are quick breads which use a leavening agent such as baking powder. They are usually served with syrup, jam or fruit. In some places, such as Germany, pancakes are made from potatoes. Although associated with the United States, pancakes were actually an Ancient Greek invention, usually served as a quick breakfast for Greek troops.
