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 ↓
Plain Vanilla Ice Cream
Ingredients
Directions
Make the custard base
Scald the milk in a saucepan but do not boil it.
In a bowl, whisk the egg yolks with the sugar and corn starch until smooth.
Gradually add the scalded milk to the egg mixture, stirring constantly.
Whip and combine
In another bowl, whip the egg whites until stiff peaks form.
Fold the whipped egg whites into the cream.
Combine the milk mixture with the whipped cream, add vanilla, and mix well.
Freeze
Freeze the mixture until firm.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the milk base and add richness as they set gently with heat.
- Egg whites
- Whipped to stiff peaks, they add airy lightness to the frozen texture.
- Cream
- Adds fat, which keeps the ice cream smooth and creamy rather than icy.
- Milk
- Forms the liquid base that the custard and cream are combined into.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the texture softer.
- Corn starch
- Stabilises the custard base and helps it thicken without curdling.
The step that matters
Gradually add the scalded milk to the egg mixture, stirring constantly.. Adding hot milk too quickly can scramble the egg yolks. Pouring slowly while stirring warms the yolks gently so the custard thickens smoothly.
