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 Souffle
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the apples
Stew the apples until soft.
Add grated lemon peel and lemon juice.
Make the custard
Line the sides and bottom of a dish with the apple mixture, about 2 inches thick.
Make a custard by heating milk and whisking in eggs until combined; let it cool.
Pour the custard into the center of the dish.
Top and bake
Beat the egg whites until stiff peaks form and spread over the top.
Sprinkle sugar over the egg whites and bake at 400°F (200°C) for a few minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Soften into a fruit base that forms the lining of the dish.
- Eggs
- Set the custard so it holds its shape when baked.
- Egg whites
- Whip into stiff peaks that create a light, airy topping.
- Milk
- Forms the liquid base of the custard, adding moisture and richness.
- Sugar
- Sweetens the topping and helps it brown in the oven.
The step that matters
Beat the egg whites until stiff peaks form. Egg whites trap air when whipped, and that air makes the soufflé rise. Under-whipped whites will not hold enough air, so the topping stays flat and dense.
Swap the apple
How well each one fits the dish's main ingredients (lemon, milk, egg, sugar):
- Vanillafits better
- Orangefits better
- Figfits better
- Applethe original
Fit is the average pairing score against lemon, milk, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
