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.
