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

What each ingredient does

Cream
Whipped into air bubbles, it gives the ice cream its light, rich body.
Egg whites
Whipped to stiff peaks, they trap air and add lightness to the frozen texture.
Sugar
Sweetens the mixture and softens the frozen texture by lowering its freezing point.

The step that matters

Beat the egg whites until stiff peaks form. Under-beaten whites collapse when folded into the cream, and over-beaten whites turn dry and grainy. Stiff peaks hold the air that keeps the ice cream light.
