In the last post, we covered eggs’ many roles in cakes, cookies, muffins, and breads. But eggs are even more versatile when we consider what they can do with air. Think about it: egg whites on their own are dense and chewy. But with air (and sugar), they become light, crisp, melt-in-your-mouth meringue cookies. Add a few more ingredients, and we can make macarons, pavlovas, cake frostings, soufflés, and sponge cakes. In this post, we’ll explore how meringue forms and how we adjust its texture for different bakes.
