Why it works: Apple and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 16,478 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Crab Apple Jelly
Ingredients
Directions
Prepare the juice
Cut Siberian crab apples into pieces without peeling them.
Cover the apples with water and stew until soft.
Pour the mixture into a jelly bag and strain to extract the juice.
Make the jelly
For every 3 pints of juice, add 2½ pints of sugar.
Boil the mixture until it reaches a jelly consistency.
Jar and cover
Pour the jelly into glasses and set them in the sun to cool.
Cover the glasses airtight.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Siberian crab apples
- Provide natural pectin and acid that help the juice set into a jelly.
- Sugar
- Sweetens the jelly and helps it set firm while preserving it.
The step that matters
Boil to jelly consistency. Pectin, acid and sugar must reach the right concentration to set. Stopping too early leaves the jelly runny, while boiling too long makes it stiff and can cause sugar to crystallise.
Swap the apple
How well each one fits the dish's main ingredients (crab, sugar):
- Raisinfits better
- Lemonfits better
- Vanillafits better
- Applethe original
Fit is the average pairing score against crab, sugar. Candidates are from the same food group and used in at least 100 recipes.
