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

What each ingredient does

Tomatoes
Provide the bulk of the jam and its fruity, tangy base as they cook down.
Sugar
Sweetens the jam and, as it thickens with the tomatoes, helps create a spreadable texture.
Sultana raisins
Add chewy texture and concentrated sweetness as they soften during the long simmer.
Orange conserve or lemon juice
Adds acidity and brightness that balance the sugar and deepen the fruit flavour.
Black walnut meats
Add crunch and a nutty flavour that contrasts with the soft jam.

The step that matters

Boil slowly for 1 hour or until thick. Sugar and tomato must simmer long enough for water to evaporate and the mixture to thicken into a jam. Too little cooking leaves it runny, while too vigorous a boil can scorch the sugar on the bottom of the pan.

Swap the tomato
