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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Siberian crab-apples
- Provide the fruit that is cooked until clear and preserved in the syrup.
- Loaf sugar
- Forms the syrup that sweetens the fruit and helps preserve it.
- Lemons
- Add acidity and aroma to the syrup and are placed on top in the bottles.
The step that matters
Boil until the apples look clear. Boiling the apples in the syrup lets sugar slowly replace the water in the fruit, so they turn clear and firm. Boiling too hard or too long can break the fruit apart.
Swap the apple
How well each one fits the dish's main ingredients (crab, sugar, lemon):
- Limefits better
- Orangefits better
- Raisinfits better
- Applethe original
Fit is the average pairing score against crab, sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
