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 Marmalade
Ingredients
Directions
Prepare the apples
Place the washed and cored crab apples in a pot with a little water.
Boil until the apples are tender.
Remove the apples and pass them through a colander.
Make and store the marmalade
Add 4 cups of sugar to the apple puree and boil until it thickens.
Pour the marmalade into stone jars, cover with paper, and store in a cool place.

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 pulp and natural pectin that give the marmalade its body.
- Sugar
- Sweetens the puree and, as it boils down, helps it thicken into a spreadable set.
The step that matters
Boiling the sugar into the puree until it thickens. Sugar and fruit pectin must be cooked together long enough to reach a gel-forming concentration. Stopping too early leaves a runny marmalade, while overcooking can make it stiff and sticky.
