Liquid

Liquid Buttermilk or sour milk provide some of the acid required to neutralize the bicarbonate of soda so the proportion of cream of tartar is reduced when these liquids are used. Otherwise, ordinary milk is used. With cheese scones, water is used because the cheese contains milk.

• To make scones richer and lighter add 1 egg to the milk but reduce the amount of milk by about 4 tablespoons.
