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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Provides the liquid base and body that the custard thickens into.
- Eggs
- Yolks thicken the sauce as they set with heat; whites add lightness.
- Sugar
- Adds sweetness and helps soften the egg yolks for smoothness.
- Vanilla
- Adds aroma and a rounded flavour to the sauce.
The step that matters
Cook until it thickens. Egg yolk proteins set when heated, so the sauce thickens gradually. Heating too fast or too long can curdle it, so cook gently and remove it from the heat once it coats a spoon.
