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

What each ingredient does

Egg yolks
Enrich the custard and add richness and a smooth, thick texture.
Egg whites
Whipped to a stiff froth, they add airiness and lightness to the mixture.
Heavy cream
Whipped and folded in, it adds fat for a creamy, tender texture.
Sugar
Makes the syrup that sweetens the mixture and helps keep it soft when frozen.
Macaroons
Stale crumbs add almond flavor and a crunchy, chewy contrast to the smooth cream.

The step that matters

Pouring the hot syrup into the eggs. Pour the syrup slowly while stirring constantly. Adding it too fast can scramble the egg yolks, while gradual addition gently cooks and thickens the custard into a smooth, stable base.
