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 ↓
Apple Trifle
Ingredients
Directions
Make the apple base
Peel, core, and slice the apples.
In a saucepan, combine the apples, lemon rind, and sugar. Boil until tender.
Remove the apples and mash them into a pulp.
Place the pulp in a glass dish.
Make the custard
For the custard, bring the milk to a boil in a saucepan.
In a bowl, beat the egg yolks.
Pour the hot milk over the yolks, then return the mixture to the saucepan.
Sweeten and add vanilla. Stir until thickened, but do not boil.
Assemble and serve
Pour the custard over the apples and top with whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Cook down into a tender pulp that forms the soft base of the trifle.
- Egg yolks
- Thicken the milk into a custard as they set with gentle heat.
- Milk
- Forms the liquid base of the custard that the egg yolks thicken.
- Whipped cream
- Adds a light, rich topping that softens the sweetness of the dish.
- Sugar
- Sweetens the apples and the custard.
The step that matters
Stir the custard until thickened, but do not boil. Egg yolks thicken through gentle heat; if the custard boils, the proteins can scramble and curdle, leaving a grainy texture instead of a smooth custard.
