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 ↓

Ingredients
Directions
Make the custard
Heat 1½ cups of milk in a double boiler until scalding, but do not boil.
Beat the yolks of 3 eggs with 4 tablespoons of sugar.
Gradually pour 1 cup of the hot milk over the egg and sugar mixture.
Return the mixture to the boiler with the remaining milk and cook until it begins to thicken.
Flavor with 1 teaspoon of vanilla or orange extract and pour into a glass dish.
Top and set
Beat the whites of the eggs to a stiff froth, adding ½ cup of currant jelly a teaspoonful at a time.
Spread the egg white mixture over the custard.
Place in a cool oven for a few moments to set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the body of the custard once heated and thickened with the egg yolks.
- Egg yolks
- Thicken the custard as they set with gentle heat, giving it richness.
- Egg whites
- Whipped to a stiff foam, they form the light, airy floating topping.
- Currant jelly
- Adds sweetness and tart fruit flavor to the beaten whites.
- Sugar
- Sweetens the yolks and helps stabilize them as they are beaten.
The step that matters
Thicken the custard gently. Egg yolks scramble and curdle if the custard gets too hot. Keeping the milk scalding and below boiling lets the yolks thicken it smoothly.
Swap the currant
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.
