Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the liquid custard into a firm, sliceable structure once chilled.
- Egg yolks
- Thicken the milk as they cook and add richness to the custard.
- Egg whites
- Whipped to stiff foam, they lighten the custard's texture.
- Milk
- Forms the liquid base that the eggs thicken and the gelatine sets.
- Lemon juice
- Adds acidity that brightens the sweetness of the custard.
The step that matters
Folding in the egg whites. Stir the stiff whites in quickly just before the custard boils. Overheating can cause the egg proteins to curdle or scramble, and the whipped foam can collapse if handled roughly.
Swap the lemon
How well each one fits the dish's main ingredients (milk, egg, sugar, vanilla):

Fit is the average pairing score against milk, egg, sugar, vanilla. Candidates are from the same food group and used in at least 100 recipes.
