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 fruit
Wash and quarter the crab-apples, removing the cores and placing them in a separate dish.
Fill a large bowl halfway with water and drop the pieces of fruit into it.
Chop the parings and imperfect parts finely and place them in a preserving kettle.
Extract the juice
Add 1 quart of water for every 2 quarts of fruit and parings, then cook gently for 2 hours.
Strain the mixture and finish as you would with apple jelly.
Cook the cores in a separate kettle covered with water for 2 hours.
After straining the first mixture, combine the remaining parts with the cooked cores and strain again to extract more juice.
Make the jelly
In the preserving kettle, mix the juice with 1 pint of sugar for every pint of juice and boil for 10 minutes.

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, pectin and tart flavour that give the jelly its body and taste.
- Sugar
- Adds sweetness and, with boiling, helps the juice thicken and set into jelly.
- Water
- Draws juice out of the fruit during gentle cooking.
The step that matters
Boiling the juice with sugar. The mixture must reach a full set point to gel. Too little boiling leaves the jelly runny, while overcooking can darken its colour and flavour.
