Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the marmalade and helps it thicken and set as it cooks.
- Rhubarb
- Adds tart body and bulk to the marmalade.
- Blanched almonds
- Add texture and crunch to the finished marmalade.
The step that matters
Boil the mixture quickly until transparent. Sugar and fruit pectin set only at a high enough concentration and temperature. Boiling briefly and hard drives off water so the marmalade thickens; boiling too long can darken the flavour and make it overly stiff.
Swap the lemon
How well each one fits the dish's main ingredients (rhubarb, orange, sugar, almond):
- Vanillafits better
- Figfits better
- Lemonthe original
- Blueberryfits about as well
Fit is the average pairing score against rhubarb, orange, sugar, almond. Candidates are from the same food group and used in at least 100 recipes.
