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 during freezing.
Finish and freeze
Once cool, add the thin cream and vanilla, then strain the mixture.
Freeze the mixture until solid.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
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 cooks and adds richness to the base.
- Flour
- Stabilizes the custard and helps prevent it from curdling or becoming grainy.
- Sugar
- Sweetens the base and lowers the freezing point, keeping the ice cream soft.
- Thin cream
- Adds fat, which gives the ice cream a smooth, creamy texture.
- Milk
- Provides liquid and milk solids that form the body of the custard.
The step that matters
Cook the custard gently while stirring. Egg proteins set when heated, so cooking over hot water with constant stirring at first keeps the custard smooth rather than curdled.
