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 Sitow
Ingredients
Directions
Prepare the apples
Pare, core, and slice the apples.
Stew the apples in a little water until soft enough to press through a colander.
Sweeten the apples to taste and transfer to a deep glass dish.
Let the apples cool.
Make the custard
Prepare a soft custard by combining milk, egg yolks, and sugar; flavor with lemon or orange.
Pour the custard over the cooled apples.
Top and serve
Whip the egg whites to a stiff froth with powdered sugar.
Heap the whipped egg whites lightly over the custard.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the fruit base, softened by stewing and pressed into a smooth layer.
- Egg yolks
- Thicken the milk into a soft custard that sets as it cools.
- Egg whites
- Whip into a stiff froth that forms the light, airy topping.
- Milk
- Forms the liquid base of the custard, giving it body and richness.
- Sugar
- Sweetens the apples and custard, balancing the tartness of the fruit.
The step that matters
Let the apples cool before pouring the custard. Pouring warm custard over the fruit can thin the custard and let it curdle or separate, so the apples should be fully cooled first.
Swap the apple
How well each one fits the dish's main ingredients (sugar, milk, egg, lemon):
- Vanillafits better
- Orangefits better
- Figfits better
- Applethe original
Fit is the average pairing score against sugar, milk, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
