The creaming method is a leavening method that introduces air into a batter. Is this considered which type of leavening process?

• A. Chemical
• B. Biological
• C. Physical
• D. Mechanical

Answer: (C)

The main idea is that creaming relies on trapping air through mechanical action, and the rise comes from physical expansion of that air. When you cream butter and sugar, you create many tiny air pockets in the batter. As the batter heats, these trapped air pockets expand, causing the batter to rise. This leavening is not due to a chemical reaction creating gas or to yeast or other organisms; it’s the physical presence and expansion of air inside the batter that leavens it. So, it’s classified as a physical leavening process because the leavening effect comes from the physical change (air expansion) rather than a chemical or biological reaction.
