Beating mixes ingredients vigorously to make them smooth or fluffy. It is more aggressive than stirring or folding. A whisk, a fork, or an electric mixer does the work. Beating incorporates air, breaks up lumps, and develops structure. Egg whites beaten into peaks are the classic example. The protein unfolds and traps air, creating a foam that can be folded into a batter or baked into a meringue. Cream beaten into whipped cream is another. The fat globules trap air, and the cream thickens and doubles in volume.

Beating is not always about air. Beating butter and sugar together, called creaming, dissolves the sugar and incorporates air, which helps a cake rise. Beating eggs with sugar until pale and thick, called the ribbon stage, creates a foam that gives a sponge cake its structure. Beating a batter smooth eliminates lumps. Each application has its own goal. The technique is the same. The result is different.

Beating requires the right tool and the right speed. A whisk is good for small quantities. An electric mixer is better for large ones. Overbeating can be a problem. Egg whites can become dry and grainy. Cream can turn into butter. Butter and sugar can separate. The cook must watch the mixture and stop at the right moment. Beating is a skill. It is also a transformation. A liquid becomes a foam. A dense mixture becomes light. The bowl is the stage. The whisk is the instrument. The result is texture.
