Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Heavy cream
Whipped into stiff peaks, it forms the airy, rich body of the filling.
Egg whites
Beaten to soft peaks, they add lightness and help the filling hold its structure.
Granulated sugar
Sweetens the filling and stabilizes the whipped structure as it dissolves.
Vanilla extract
Adds aroma and a rounded flavor that complements the cream and sugar.

The step that matters

Gently fold the egg whites into the whipped cream. Folding keeps air trapped in both the whites and the cream. Stirring vigorously deflates the mixture, leaving a dense, heavy filling instead of a light one.
