Why it works: Apple and lemon are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 7,551 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Our Favorite Apple Meringue
Ingredients
Directions
Prepare
Half-fill your dish with rich apple sauce flavored with lemon rind.
Make the custard and topping
Make a boiled custard using only the yolks of the eggs and pour it over the apples.
Whip the egg whites to make a meringue and pile it prettily over the custard.
If your dish can withstand the heat, set it in the oven to brown slightly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the boiled custard so it sets into a smooth, creamy layer.
- Egg whites
- Whipped into a foam that forms the light, airy meringue topping.
- Rich apple sauce
- Provides the moist, fruity base layer that the custard sits on.
The step that matters
Whipping the egg whites for the meringue. Egg whites must be beaten until they hold stiff peaks, because the foam traps air and gives the meringue its volume. Any trace of fat or yolk in the whites can stop them from whipping properly.
Swap the apple
How well each one fits the dish's main ingredients (sauce, lemon, egg):
- Limefits better
- Orangefits better
- Avocadofits better
- Applethe original
Fit is the average pairing score against sauce, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
