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
Place the crab-apples in enough water to cover them and boil until tender.
Mash the apples with a spoon and strain through a jelly bag.
For every pint of juice, use 1 pound of sugar.
Heat the sugar in the oven and the juice in a preserving kettle.
Make and seal the jelly
Once the sugar is hot, add it to the juice and boil for 30 minutes.
Pour the jelly into glasses, cover with brandied paper, and seal tightly.

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
- Red crab-apples
- Provide the fruit pectin and tart flavour that set the jelly once the juice is boiled.
- Sugar
- Sweetens the jelly and helps it set firm by binding water and pectin together.
The step that matters
Boiling the sugar and juice for 30 minutes. Boiling drives off water and concentrates the pectin and sugar so the jelly reaches its setting point. Too short a boil leaves it runny, while over-boiling can darken and toughen it.
