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 Sauce
Ingredients
Directions
Make the custard
In a saucepan, combine the egg yolks, milk, and castor sugar to make a custard.
Add the vanilla essence to the custard and stir well.

Gently mix the custard and egg whites until well combined.
Serve the sauce hot or cold.

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 the milk.
- Egg whites
- Whipped to stiff foam, they lighten the sauce and give it an airy texture.
- Milk
- Provides the liquid base that the egg yolks thicken into custard.
- Castor sugar
- Sweetens the custard and dissolves easily into the warm liquid.
The step that matters
Gently mix the custard and egg whites. Whipped egg whites lose their air if overmixed or stirred vigorously, which makes the sauce dense. Folding slowly keeps the foam intact while blending the hot custard evenly through it.
