Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sugar
Sweetens the preserve and, with the fruit, helps it thicken and set as it cooks down.
Rhubarb
Provides the tart base and bulk of the preserve, with pectin and acidity that aid setting.
Figs
Add body, sweetness and a soft texture to the chopped fruit mixture.
Oranges
Add acidity and aromatic citrus flavour, and their peel and pulp help the mixture set.
Walnut meats
Add crunch and a toasted, nutty flavour that contrasts with the soft fruit.

The step that matters

Cook slowly, stirring frequently, until the mixture reaches the consistency of marmalade. Sugar and fruit must reduce until the concentration is high enough for the pectin to gel as it cools. Stopping too early leaves a runny preserve, while cooking too long or too hot can scorch the sugar and darken the flavour. Frequent stirring prevents sticking at the bottom of the pan.
