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 ↓
Apple Snow
Ingredients
Directions
Prepare the apples
Pare, quarter, and core 4 sour apples.
Steam the apples until soft.
Rub the steamed apples through a sieve to obtain ½ cup of apple pulp.
Make and serve the snow

Gradually add the sweetened apple pulp to the egg whites.
Pile the mixture lightly on a dish and serve with custard sauce. Optionally, add lemon juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten into a stiff foam that gives the dessert its light, airy structure.
- Apple pulp
- Supplies the fruit flavour and body, folded into the foam to make it smooth and soft.
- Powdered sugar
- Sweetens the apple pulp so the finished snow tastes balanced.
The step that matters
Beating the egg whites until stiff. Egg whites hold air only when fully whipped and free of grease or yolk. Under-beaten whites collapse when the apple pulp is folded in, leaving a dense, watery dessert.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (apple, egg, sugar):
- Vanillafits better
- Pearfits better
- Figfits better
- Lemonthe original
Fit is the average pairing score against apple, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
