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 ↓

Ingredients
Directions
Make the custard
In a saucepan, bring the milk to a boil.
Stir in the beaten egg yolks, sugar, and salt, and let it boil for a moment while stirring constantly.
Pour the mixture into a covered dish and season with vanilla.
Top and cover
Beat the egg whites until stiff peaks form, then drop spoonfuls on top of the custard.
Cover immediately to trap steam and cook the egg whites.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the custard, providing creaminess and body.
- Egg yolks
- Thicken the custard as they set, giving it a rich, smooth texture.
- Sugar
- Sweetens the custard and balances the richness of the yolks and milk.
- Egg whites
- Whipped to stiff peaks, they form the light, airy floating topping.
The step that matters
Cover immediately after topping. Egg whites are cooked by the trapped steam rather than direct heat. Covering at once keeps the steam in so the meringue sets and stays light instead of drying or weeping.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
