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 pulp and skins that form the body and flavour of the jam.
- Sugar
- Sweetens the jam and helps it set into a thick, spreadable texture.
The step that matters
Cook until the skins are soft. Grape skins are tough and hold much of the pectin and tartness. If they are not fully softened before the jam is jarred, the texture stays chewy and the jam may set unevenly.
