What is used to whisk air in to a mixture?

A whisk is typically used to incorporate air into a mixture. It consists of a handle with a series of thin wires or loops that create a frothy texture when moved quickly through the mixture. This process is essential for recipes like meringues or whipped cream, where incorporating air helps achieve volume and lightness. Electric mixers can also be used for this purpose, providing a more efficient way to aerate ingredients.
