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

What each ingredient does

Eggs
Thicken the custard and add richness and structure to the frozen cream.
Sugar
Sweetens the base and helps keep the ice cream smooth and scoopable.
Sweet cream
Adds fat for a rich, creamy texture.
Milk
Forms the liquid base that the chocolate and eggs are combined into.
Chocolate
Provides the main chocolate flavor and some fat for body.

The step that matters

Return to the stove and bring to a boil again. Egg yolks thicken the custard as they heat, but if it boils too hard or too long they can scramble, leaving lumps. Heat gently and stop once the custard coats a spoon.

Swap the lemon
