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

What each ingredient does

Quinces
Provide the pectin and tart flavour that give the marmalade its body and set.
Sugar
Sweetens the fruit and, as it dissolves and concentrates, helps the mixture thicken and keep.
Lemon juice
Adds acidity that brightens the flavour and supports pectin setting.
Oranges
Contribute juice and pulp for extra pectin, citrus aroma and sweetness.

The step that matters

Cooking until the mixture thickens. Cook until the quinces are soft and the mixture thickens, since the sugar and pectin set as water evaporates. Undercooking leaves it runny and unable to keep well.

Swap the quince

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

  1. Limefits better
  2. Vanillafits better
  3. Blueberryfits better
  4. Quincethe original

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