The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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.
