Shared aroma: beta-damascenone (apple, rose).
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
- Apples, grapes, or plums
- Natural pectin and acid in the fruit help the jelly set.
- Sugar
- Sugar adds sweetness and helps the juice thicken and gel as it cools.
The step that matters
Boiling the syrup. Boiling long enough concentrates the mixture so it can gel as it cools. Too little boiling leaves the jelly runny, while too much can make it stiff or sugary.
