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

What each ingredient does

Oranges
Their peel and pulp provide the bitter-sweet flavour and natural pectin that help the marmalade set.
Lemon
Adds acidity, which brightens the flavour and supports pectin setting.
Grapefruit (in the method)
Adds bitterness and aromatic peel oils, giving the marmalade its distinctive character.
Sugar (in the method)
Sweetens the marmalade and, with heat, helps it thicken and set into a jelly.

The step that matters

Boiling until it jellies. Sugar, acid and pectin set into a gel only at the right concentration. Boiling too briefly leaves the marmalade runny, while overcooking can make it stiff and dull in flavour.

Swap the grape

How well each one fits the dish's main ingredients (orange, lemon):

  1. Limefits better

  4. Grapethe original

Fit is the average pairing score against orange, lemon. Candidates are from the same food group and used in at least 100 recipes.
