Batters are semiliquid mixtures containing flour or other starch. They are used in deep-frying to give a crisp, flavorful, golden brown coating. There are many formulas and variations for batters:
- Many liquids are used, including milk, water, and beer.
- Eggs may or may not be used.
- Thicker batters make thicker coatings. Too thick a batter makes a heavy, unpalatable coating.
- Leavenings are frequently used to give a lighter product. These may be:
- Baking powder
- Beaten egg whites
- Carbonation from beer or seltzer used in the batter
