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 ↓
Boiled Custards
Ingredients
Directions
Make the custard
Scald the milk in a saucepan.
Beat the egg yolks lightly and mix in the sugar.
Pour the hot milk over the yolk mixture and stir well.
Fold in the beaten egg whites and return the mixture to the heat.
Stir until the custard thickens, then let it cool.
Pour the custard into small cups.
Top with meringue
Whip the egg whites with the powdered sugar until stiff to make the meringue.
For a pink meringue, substitute half the sugar with currant jelly and whip until frothy.
Heap a large spoonful of meringue on each cup of custard.

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 set when gently heated, giving it body and richness.
- Egg whites
- Whipped into a stiff foam that forms the light, airy meringue topping.
- Milk
- Forms the liquid base of the custard that the eggs thicken.
- Sugar
- Sweetens the custard and helps stabilize the whipped egg white meringue.
- Currant jelly
- Adds sweetness, flavor and pink color to the optional meringue.
The step that matters
Stir until the custard thickens. Egg yolks set when heated, but if the custard gets too hot it can curdle or turn grainy. Stir constantly over gentle heat and remove it once it coats a spoon.
Swap the currant
The recipe marks currant as optional. How well each one fits the dish's main ingredients (milk, egg, sugar, vanilla):
- Figfits better
- Peachfits better
- Blueberryfits better
- Currantthe original
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.
