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 apples
Quarter the apples and remove any black seeds or spots.
Place the apples in a preserving kettle with ½ cup of water to prevent burning.
Cook on the fire, adding more water as it evaporates, until the apples boil to a pulp.
Strain the apples through a coarse flannel.
Make the jelly
For each pint of juice, add 1¼ pounds of refined sugar in a porcelain kettle.
Pour the juice over the sugar, stirring frequently.
Skim the mixture before it boils and cook for about 20 minutes, or until it congeals on a spoon.
Pour into hot jelly glasses and cover when cold.

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
- Ripe crab apples
- Provide the pectin and acidity that let the juice set into jelly.
- Refined sugar
- Sweetens the jelly and helps it thicken and set as it cooks.
The step that matters
Skim the mixture before it boils and test for set on a spoon. Skimming before boiling removes foam and impurities for a clear jelly. Cooking must stop at the gel point, when the mixture congeals on a spoon; undercooking leaves it runny, while overcooking makes it stiff.
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.
