Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Provides the main body and tartness of the preserve, softening into the syrup as it cooks.
- Sugar
- Sweetens the fruit and, at high concentration, helps it set and preserves it.
- Vinegar
- Adds acidity that brightens the flavour and balances the sweetness of the syrup.
- Cloves
- Contribute warm, aromatic spice flavour that infuses into the syrup from the muslin bag.
- Cinnamon
- Adds warm, sweet aroma that infuses into the syrup from the muslin bag.
The step that matters
Cook until clear. Rhubarb must be cooked in the thickened syrup long enough for the pieces to turn translucent and the sugar to penetrate. Stopping early leaves the fruit firm and the syrup thin, while overcooking can break the pieces down and darken the preserve.
