What is a pound cake?
The classic recipe for a pound cake includes 1 pound each of butter, sugar, eggs and flour. It is a thick, dense moist cake. The mixing of the butter incorporates enough air to provide the support a pound cake needs. Mixing the butter with the sugar is done before all the other ingredients are added. During baking, the air in the butter expands and the moisture in the eggs turns to steam, raising and lightening the cake.
