Shared aroma: beta-damascenone (apple, rose).
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Full grown unripe grapes
- Provide the fruit juice that, with sugar, forms the jelly.
- Granulated sugar
- Sweetens the jelly and helps it set as it boils and cools.
The step that matters
Boil the sugar and juice for 20 minutes. Boiling concentrates the juice and dissolves the sugar so the mixture can reach the thickness needed to gel. Too little boiling may leave the jelly runny, while the sugar helps the pectin set as it cools.
