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

What each ingredient does

Vanilla
Gives the ice cream its characteristic flavour.
Sugar
Sweetens the base and softens the texture once frozen.
Milk
Forms the liquid base that the custard thickens in.
Egg yolks
Thicken the base into a custard as they set with gentle heat.
Cream
Adds fat, which makes the ice cream rich and smooth.
Lemon juice
Adds a little acidity that brightens the sweet, creamy flavour.

The step that matters

Thickening the egg yolks. Egg yolks thicken the base only when heated gently while stirring constantly. If the mixture gets too hot, the proteins tighten and scramble, leaving a grainy custard instead of a smooth one. Keeping the heat low and stirring steadily prevents this.

Swap the lemon

How well each one fits the dish's main ingredients (vanilla, sugar, milk, egg, cream):
