Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓

Ingredients
Directions
Make the custard
Scald the milk in a saucepan.
Mix the cornstarch with ½ cup sugar and stir into the hot milk.
Stir constantly until thickened, then cook for 10 minutes, stirring occasionally.
Beat the eggs with a few grains of salt and ½ cup sugar.
Add a little of the hot mixture to the eggs and blend well.
Stir the egg mixture into the rest of the hot mixture.
Cook until the egg mixture is set, then strain.
Finish and freeze
Once cold, add the rich cream and vanilla.
Freeze the mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as they set and add richness to the base.
- Cornstarch
- Thickens the hot milk so the custard holds body before freezing.
- Rich cream
- Adds fat, which makes the frozen ice cream smooth and creamy.
- Sugar
- Sweetens the base and softens the texture of the frozen mixture.
The step that matters
Cook the egg mixture until set. Eggs thicken as they heat, but overheating can scramble them into lumps. Adding a little hot milk first gently warms the eggs so they blend smoothly into the base.
