What Makes Meringue Thicken? Understanding the Science Behind Perfect Meringue
Discover how air, acid, and sugar work together to thicken meringue and create stiff peaks in this quick explanation.

Meringue thickens due to the incorporation of air into egg whites when they are whipped. Adding an acid, like cream of tartar or lemon juice, stabilizes the egg whites, allowing the meringue to reach stiff peaks and hold its shape. Sugar also helps by interacting with the proteins to create a more stable foam.
FAQs & Answers
- Why does adding cream of tartar help meringue thicken? Cream of tartar acts as an acid that stabilizes egg white proteins, allowing them to hold air better and reach stiff peaks.
- How does sugar contribute to meringue stability? Sugar interacts with the egg white proteins to strengthen the foam, making the meringue more stable and less likely to collapse.
- What happens when you whip egg whites to make meringue? Whipping egg whites incorporates air, which creates a foam that thickens as air bubbles are trapped by the protein structure.
