CREAMING
Creaming
Creaming is used to refer to several different culinary processes. Creaming, in baking, is the technique of blending ingredients — usually granulated sugar — together with a solid fat like shortening or butter. The technique is most often used in making buttercream, cake batter or cookie dough. The dry ingredients are mixed or beaten with the fat until it becomes light and fluffy and increased in volume, due to the incorporation of tiny air bubbles. These air bubbles, locked into the semi-solid fat, remain in the final batter and expand as the item is baked, serving as a form of leavening agent.The above text is a snippet from Wikipedia: Creaming (food)
