Meringues whip egg whites into sweet peaks

Meringues are delicate desserts made by whipping egg whites with sugar until they form stiff, glossy peaks, then baking them into light, crisp treats. This process relies on the science of protein denaturation: as egg whites are beaten, air bubbles are incorporated, and the proteins unfold and bond to trap those bubbles, creating volume and structure. Adding sugar stabilizes the foam, preventing collapse during baking. The result is a melt-in-your-mouth texture that's both crunchy on the outside and soft within.
