Why it works: Apple and quince work together. They rank in the top 1% of all ingredient pairs, and cooks put them together in 506 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tart apples
- Provide bulk, natural pectin and tart flavour that give the puree body.
- Quince
- Adds fragrant aroma and pectin that helps the puree thicken as it cooks.
- Egg yolks
- Enrich the puree and thicken it gently when heated.
- Egg whites
- Whipped to a foam, they lighten the mixture and give it an airy texture.
- Sugar
- Adds sweetness and balances the tartness of the fruit.
The step that matters
Stir in the egg whites when the mixture is cool. Frothed egg whites are a foam that heat collapses. Adding them to a cooled mixture keeps the air trapped, so the puff stays light instead of turning dense and flat.
Swap the quince
How well each one fits the dish's main ingredients (apple, egg, sugar):
- Vanillafits better
- Pearfits better
- Figfits about as well
- Quincethe 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.
