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

What each ingredient does

Sugar
Sweetens the jam and, with heat and acid, helps it thicken and set.
Currant juice
Adds tartness and natural pectin that helps the jam gel.
Raspberry juice
Provides the main raspberry flavour and deep red colour.
Raisins
Add chewy texture and concentrated sweetness as they soften in the cooking.
Oranges
Add bright, slightly bitter aroma and acidity, with peel adding pectin.

The step that matters

Boil for the full 1½ hours. Sugar and fruit acids need sustained heat to concentrate the liquid and activate the pectin, so the jam thickens and sets. Stopping early can leave it runny.

Swap the currant

How well each one fits the dish's main ingredients (sugar, red raspberry, raisin, orange):
