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 Compote
Ingredients
Directions
Prepare the apple
Wipe, quarter, core, and peel the apple; cut it into ½‑inch thick slices.
Make the compote
Make a syrup by combining water, sugar, and lemon rind; cook for two minutes, then remove the rind.
Add the apple slices to the syrup, cover, and cook slowly until the apple is clear.
Carefully remove the apple, add lemon juice to the syrup, and strain it over the apple.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apple
- Provides the fruit body, which softens and turns translucent as it cooks gently in the syrup.
- Sugar
- Sweetens the syrup and helps form the liquid that the apple slices cook in.
- Lemon juice
- Adds acidity that brightens the sweetness and balances the flavour of the syrup.
The step that matters
Cook the apple slowly under cover. Gentle, covered cooking softens the apple evenly without breaking the slices apart. Rapid boiling can break down the fruit and make the syrup cloudy, so the apple may turn mushy before it is clear.
