Which mixing method incorporates air for leavening?

• A. Sifting dry ingredients
• B. Creaming solid fat with sugar
• C. Kneading dough
• D. Whipping eggs

Answer: (B)

Air incorporation during the creaming method creates leavening. When solid fat (like butter) is beaten with sugar, the mixture becomes pale and fluffy as tiny air pockets are formed and trapped throughout. These pockets expand as the batter heats, leavening the cake and producing a light, tender crumb. Sifting dry ingredients can lighten batter slightly but doesn’t generate the sustained air pockets needed for leavening. Kneading develops gluten and yields a denser structure rather than relying on air. Whipping eggs does introduce air, but it’s a different technique used for other textures; the creaming method is the classic approach for leavening cakes by trapping air in fat and sugar.
