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

What each ingredient does

Egg yolks
Thicken the custard base and add richness as they set with gentle heat.
Cream
Adds fat and richness, giving the frozen ice cream a smooth, creamy texture.
Sugar
Sweetens the base and lowers the freezing point, keeping the ice cream softer.
Milk
Provides the liquid base that the sugar and yolks are dissolved and set into.
Lemon juice
Adds acidity that brightens the flavour and balances the sweetness.

The step that matters

Incorporating the egg yolks over low heat. If the heat is too high or stirring stops, the yolk proteins can scramble and curdle the custard. Constant stirring over low heat lets them thicken it smoothly.

Swap the lemon
