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

What each ingredient does

Naval oranges
Provide the bitter peel and pulp that give marmalade its characteristic flavor and pectin.
Lemons
Add acidity and extra pectin, helping the marmalade set.
Granulated sugar
Sweetens the marmalade and, with boiling, helps it thicken into a gel.
Water
Softens the thin-sliced fruit and draws out pectin during the long soak and boil.

The step that matters

Boil quickly until it reaches a jelly consistency. Sugar must be added before a rapid boil so the mixture reaches the gel point. Overcooking can make the marmalade stiff, while undercooking leaves it runny and unset.
