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

What each ingredient does

Egg yolks
Thicken the cream and add richness through their fat and emulsifying proteins.
Egg whites
Whipped to stiff peaks, they add lightness and air to the mixture.
Sugar
Sweetens the custard and softens its texture once frozen.
Cream
Provides fat that gives the frozen dessert a smooth, rich mouthfeel.

The step that matters

Stirring the custard as it thickens over the cream. Egg yolks set at about 160°F, so the mixture must be stirred while it thickens to keep the proteins from curdling into lumps. Straining afterward removes any bits that do form.
