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 apples, then cut them in halves.
Place the apples in a pot and cover with cold water.
Stew the apples over low heat until they become a pulp.
Pour the pulp into a jelly bag and let the juice drain.
Make the jelly
Combine 1 pint of the juice with 1 pound of sugar in a pot.
Boil the mixture for about 20 minutes, removing any scum.
Test the jelly by cooling a small amount; it should form a jelly.
Partly cool the jelly and store it as directed for jellies.

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 pectin and acidity that give the jelly its juice and set.
- Sugar
- Sweetens the jelly and helps it set by binding water and pectin.
The step that matters
Boiling the juice with sugar. The mixture must reach a full, steady boil so pectin and sugar can set the jelly; a weak boil leaves it runny. Removing scum keeps the jelly clear. Testing a cooled sample confirms the set before storing.
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.
