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

What each ingredient does

Gelatin
Sets the liquid mixture into a firm, sliceable chilled dessert.
Egg yolks
Enrich the custard, adding richness and helping thicken it when heated.
Beaten egg whites
Whip air into the mixture, giving it a light, airy texture.
Cream
Adds fat and richness, giving a smooth, creamy mouthfeel.
Grated chocolate
Provides chocolate flavor and deepens the color of the custard.
Milk
Forms the liquid base that the gelatin dissolves into and the custard is built on.

The step that matters

Folding in the beaten egg whites. The custard must be cooled before folding, since heat would deflate the whipped whites. Gentle folding keeps the air bubbles that give the dessert its light texture.
