Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Provides the tart flavour and body that balances the sweetness of the sugar.
- Pineapple
- Adds sweetness and a tropical aroma, and softens to become part of the jam's texture.
- Sugar
- Sweetens the fruit, draws out moisture, and helps the marmalade thicken and set when boiled.
The step that matters
Boil the rhubarb and pineapple together for 20 minutes. Once the fruit is combined, boiling concentrates the sugar and pectin as water evaporates. Boiling too briefly leaves the marmalade runny, while overboiling can scorch the sugar and darken the flavour.
Swap the pineapple
How well each one fits the dish's main ingredients (rhubarb, sugar):
