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 ↓
Vanilla Ice Cream II
Ingredients
Directions
Make the custard
Mix flour, sugar, and salt in a bowl.
Add the slightly beaten egg and gradually stir in the scalded milk.
Cook the mixture over hot water for 20 minutes, stirring constantly at first. If the custard appears curdled, it will smooth out when frozen.
Finish and freeze
Add the thin cream and vanilla.
Strain the mixture.
Freeze the mixture until solid.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the custard as it heats, giving the base body and structure.
- Flour
- Stabilizes the custard and helps keep it smooth during cooking.
- Milk
- Forms the liquid base that the egg and sugar cook into custard.
- Sugar
- Adds sweetness and softens the frozen texture of the ice cream.
- Thin cream
- Adds fat for richness and a smooth, creamy mouthfeel.
- Vanilla
- Adds the main aroma and flavour.
The step that matters
Cook the custard gently over hot water. Egg proteins set when heated, so high heat or not stirring can curdle the custard. Gentle, constant stirring keeps it smooth and thickened.
