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
Ingredients
Directions
Make the custard
In a saucepan, combine milk, sugar, vanilla extract, and egg yolks.
Stir with an egg beater until the mixture thickens without boiling.
Strain the mixture and let it cool.
Freeze the ice cream
Place the tin freezer in a pail and surround it with chopped ice and rock salt.
Pour the cream into the tin can and cover it.
Turn the handle of the pail rapidly for a few moments.
Remove the cover and detach any frozen cream from the sides with a spoon.
Replace the cover and continue turning the handle, pressing the cream down with the spoon until smooth.
Pack and serve
Once thoroughly frozen, transfer the ice cream to a mold, cover with thick paper, and secure the lid.
Place the mold in a bowl surrounded by chopped ice and rock salt.
Before serving, dip the mold in warm water for a few seconds to release the ice cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard and add richness as they set gently with heat.
- Milk
- Forms the liquid base that freezes into the body of the ice cream.
- Sugar
- Sweetens the base and lowers its freezing point so it stays scoopable.
- Rock salt
- Lowers the temperature of the surrounding ice so the cream can freeze.
The step that matters
Stir the custard without boiling. If the egg mixture boils, the yolks can scramble and curdle, leaving a grainy texture. Stirring gently until it thickens keeps the custard smooth.
