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

What each ingredient does

Eggs
Whipped whites trap air for a light, airy structure, and the yolks thicken the mixture as they cook.
Cream
Whipped cream adds richness and a smooth, airy texture to the frozen dessert.
Sugar
Sugar, boiled into a syrup, sweetens the dessert and keeps it soft rather than rock hard when frozen.

The step that matters

Boil the egg mixture in the double boiler while stirring constantly. Egg proteins set when heated, so the yolks can scramble or curdle if they get too hot or sit still. Constant stirring spreads heat evenly and keeps the custard smooth.
