Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Cocoa Ice Cream

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 and add richness as they set during gentle cooking.
- Cream
- Adds fat for a smooth, rich texture and softer freezing.
- Cocoa
- Provides the chocolate flavor and deep color of the ice cream.
- Sugar
- Sweetens the base and helps keep the ice cream from freezing rock-hard.
- Corn starch
- Thickens the base and gives a smoother, less icy texture.
The step that matters
Cook the milk and cocoa mixture in the double boiler. Gentle heat over simmering water keeps the mixture from scorching while the starch thickens it. Overheating can curdle the egg yolks added later, so the base must stay at a controlled temperature.
Swap the cocoa
How well each one fits the dish's main ingredients (cinnamon, sugar, egg, corn, cream, butter, milk):
