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

What each ingredient does

Grapes
Skins and pulp provide the fruit body, natural pectin and flavour of the marmalade.
Sugar
Sweetens the mixture and, as it cooks, helps the juice thicken into a jelly-like set.
Oranges
Add citrus acidity and bitter aroma, and their peel contributes pectin to help set the jelly.
Lemon
Adds acidity and extra pectin, helping the marmalade brighten in flavour and set.
English walnuts
Add crunch and a nutty flavour that contrasts with the soft, jelly-like texture.
Raisins
Add chewy texture and concentrated sweetness to the finished marmalade.

The step that matters

Cook until the juice forms a light jelly. Pectin and sugar must be cooked to the right concentration to set. Undercooking leaves the marmalade runny, while overcooking can make it stiff and dull in flavour.

Swap the raisin
