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
- Egg yolks
- Thicken the custard as they cook gently, giving it body and a smooth, rich texture.
- Milk
- Forms the liquid base of the custard and the poaching liquid for the egg whites.
- Egg whites
- Whipped until stiff, they add airy lightness and hold their shape when poached.
- Sugar
- Sweetens the custard and the topping, and helps the whipped whites stay stable.
- Vanilla
- Adds a warm aroma that rounds out the sweet custard flavour.
The step that matters
Cooking the custard over heat. Egg yolks thicken gently as they warm. If the mixture gets too hot or cooks too long, the proteins tighten and the custard can curdle or turn grainy, so keep the heat moderate and stir.
“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.
