Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Custard
Ingredients
Directions
Make the custard
In a saucepan, gently heat the milk with a grain or two of salt.
In a bowl, whisk the egg yolks and sugar together.
Once the milk is warm, slowly stir it into the egg mixture.
Add the cream and flavor with brandy or vanilla.
Bake and serve
Butter a round deep dish and pour in the custard.
Place the dish in a pan of boiling water, ensuring the water does not touch the custard.
Simmer gently for 1 to 1.5 hours until firm in the middle.
Serve cold, garnished with chopped macaroons or vanilla.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Set the custard as they cook, giving it a firm, sliceable structure.
- Milk
- Provides the liquid base that the egg yolks set into a smooth custard.
- Sugar
- Sweetens the custard and balances the richness of the yolks and cream.
- Cream
- Adds fat, which gives the custard a richer, softer texture.
The step that matters
Simmer gently in a water bath. Egg proteins set at temperatures close to boiling, so the custard can curdle or become grainy if cooked too hard. Gentle heat in a water bath, with the water kept off the custard, lets it set evenly and firm in the middle.
