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

What each ingredient does

Rhubarb: Provides the tart fruit body and most of the bulk of the conserve.
Sugar: Adds sweetness and, as it concentrates, helps thicken the fruit into a spreadable set.
Orange: Its grated rind adds bright citrus aroma and a slight bitterness.
Walnut meats: Add crunch and contrast to the soft, cooked fruit.
Seeded raisins: Add chewy texture and concentrated sweetness as they soften in the syrup.

The step that matters

Simmering while stirring. As water evaporates, the sugar-rich mixture thickens and sticks to the bottom of the pot, so frequent stirring prevents scorching and burnt flavour.
