Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Provides fat and richness, giving the frozen result a smooth, creamy texture.
- Egg yolks
- Add emulsifying fat and body that help the custard base set smooth and rich.
- Egg whites
- Whipped stiff, they trap air that makes the frozen ice cream lighter.
- Corn starch
- Thickens the custard base when it is heated to a boil.
The step that matters
Bring the starch mixture just to a boil. Cornstarch only thickens once it reaches a boil, so the base must be brought to a boil after the starch is added. Cooking it only a few seconds keeps the custard from overheating and the egg yolks from scrambling.
