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

What each ingredient does

Oranges
Provide the bitter peel and pulp that give marmalade its characteristic flavour and pectin.
Lemons
Add acidity and additional pectin, helping the marmalade set.
Sugar
Sweetens the marmalade and, at high concentration, helps it set and keep.

The step that matters

Adding the sugar. Sugar should be added only after the fruit is fully tender. Adding it too early can toughen the peel, and the set depends on sugar, acid and pectin reaching the right balance during boiling.
