Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Forms the bulk of the jam and provides its tart flavour.
- Sugar
- Sweetens the jam and helps it thicken and keep.
- Lemon juice
- Adds acidity that brightens the flavour and supports setting.
- Almonds
- Add texture and a nutty flavour as thin fillets.
The step that matters
Boiling for 45 minutes while stirring and skimming. Sugar-rich jam can scorch on the base of the pan, so constant stirring prevents burning. Skimming removes foam, giving a clearer, cleaner jam that thickens as water evaporates.
