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

What each ingredient does

Egg yolks
Add richness and help thicken the custard as it cooks.
Cream
Adds fat and a smooth, creamy texture to the finished ice cream.
Cocoa
Provides the chocolate flavor and deep color.
Sugar
Adds sweetness and softens the texture by lowering the freezing point.
Corn starch
Thickens the mixture so the custard becomes smooth and stable.

The step that matters

Cooking the milk mixture in a double boiler. Cooking gently over indirect heat keeps the thickening starch and egg proteins from scorching or curdling, so the custard stays smooth.
