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 ↓

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 cook and add richness and structure to the frozen ice cream.
- Sugar
- Sweetens the base and helps keep the frozen texture softer and smoother.
- Rich milk
- Forms the liquid base of the custard, carrying flavour and setting with the eggs.
- Rich cream
- Adds fat, which makes the frozen ice cream richer and creamier in texture.
- Vanilla bean
- Infuses aroma and flavour into the milk while it is scalded.
The step that matters
Thickening the custard over a double boiler. Eggs thicken when heated gently, but overheating can scramble them into lumps. Stirring constantly over indirect heat keeps the custard smooth and lightly thickened before it cools and is frozen.
