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
Make the apple pulp
Peel, core, and quarter the apples.
Place them in a saucepan with the lemon rind and enough water to prevent burning.
Cook until tender, then remove the lemon peel.
Mash the apples into a pulp and let cool.
Make the snow and serve
Beat the egg whites until stiff, then fold in the apple pulp.
Add the sifted sugar and whisk until the mixture is very stiff.
Serve in a glass dish or small glasses, garnished with barberries or jelly strips.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Cook down into a pulp that gives the dessert its body and fruity flavour.
- Whites of 10 eggs
- Whipped into a foam that traps air and gives the dessert its light, snowy structure.
- Pounded sugar
- Sweetens the pulp and stabilises the whisked whites, helping the mixture hold its stiff shape.
The step that matters
Whisk the sugar into the whites until very stiff. Egg white foam is fragile and can collapse if overbeaten or deflated. Sugar added once the whites are stiff helps stabilise the foam, and the pulp must be cool so it does not melt or loosen the structure when folded in.
Swap the apple
How well each one fits the dish's main ingredients (egg, lemon, sugar):
- Orangefits better
- Vanillafits better
- Limefits better
- Applethe original
Fit is the average pairing score against egg, lemon, sugar. Candidates are from the same food group and used in at least 100 recipes.
