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
- Grapes
- Provide the fruit flavor, natural pectin and acidity that help the preserve set.
- Sugar
- Adds sweetness and, as it concentrates, helps the liquid thicken and keeps the preserve stable.
The step that matters
Add the sugar and cook until the liquid thickens. Sugar, pectin and acid set together only at a high enough concentration. Stopping too early leaves the preserve runny, while cooking too long makes it stiff and may crystallize as it cools.
