Why it works: Apple and milk are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 4,104 recipes. Both carry 4-heptenal, which smells creamy, biscuit. The science ↓
Apple Trifle
Ingredients
Directions
Make the custard
Heat the milk and pour it over the beaten yolks and sugar.
Return the mixture to a saucepan and stir until it begins to thicken, about 8 minutes.
Set aside in a shallow vessel to cool.
Assemble the trifle
Beat the egg whites until very stiff, then gradually fold them into the apple sauce.
Once combined, pile the mixture into a glass dish and pour the cold custard around the base.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard, while whites are beaten to give the apple mixture a light, airy structure.
- Milk
- Forms the liquid base of the custard, which thickens as the egg proteins set with gentle heat.
- Apple sauce
- Provides the fruit body and moisture of the trifle, sweetened and flavored with lemon peel.
- Sugar
- Sweetens the custard and helps keep the egg yolks smooth when heated.
The step that matters
Thickening the custard. Stir gently over moderate heat until it just begins to thicken. Egg proteins set around 160°F to 180°F, so overheating can curdle the custard into grainy lumps, while underheating leaves it thin.
Swap the apple
How well each one fits the dish's main ingredients (sauce, lemon, egg, milk, sugar):
