Why it works: Vanilla and milk 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 ↓
Ice Cream
Ingredients
Directions
Make the custard
Put 1 pound of sugar, the split vanilla bean, and 2 quarts of milk over boiling water.
Beat 6 eggs with ½ pound of sugar and add to the hot milk.
Cook until slightly thickened, then remove from heat and let cool.
Finish and freeze
Once cool, add 1 quart of rich cream and whip briskly for a few moments.
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 cook and give the ice cream a rich, smooth body.
- Milk
- Forms the liquid base that the eggs thicken and the freezing firms up.
- Sugar
- Sweetens the base and lowers the freezing point so the ice cream stays scoopable.
- Rich cream
- Adds fat, which makes the frozen texture creamy and smooth rather than icy.
- Vanilla bean
- Infuses the milk with vanilla aroma as it heats.
The step that matters
Cook until slightly thickened. Heating the egg mixture gently thickens it; if it gets too hot the eggs can scramble, leaving a grainy texture. Cooling it fully before adding the cream keeps the cream from melting and loosening the base.
