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
Wash and stem the crab-apples, then cut them in half.
Place the apples in a pot and cover them with cold water.
Stew the apples until they become a pulp.
Pour the pulp into a jelly bag and let the juice drain.
Make the jelly
For the jelly, combine 1 pint of juice with 1 pound of sugar in a pot.
Boil the mixture for about 20 minutes, removing any scum.
Check if the jelly sets by cooling a small amount on a plate.
Once ready, let the jelly cool partially before transferring it to jars.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Apple and sugar barely smell alike, yet cooks put them together in 16,478 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Crab-apples
- Provide the fruit juice that, with sugar, forms the jelly's flavour and body.
- Sugar
- Sweetens the jelly and helps it set by binding with the fruit's pectin and water.
The step that matters
Checking the set on a cold plate. Jelly sets as the concentration of sugar and pectin rises during boiling, and the cold-plate test shows whether it has reached that point. Stopping too early leaves runny jelly, while boiling too long can make it stiff or cloudy.
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.
