What each ingredient does

Oranges
Rind and pith supply natural pectin and bitterness that help the marmalade set and flavour it.
Sugar
Sweetness and preservation, and with cooking it concentrates the mixture so it sets to a gel.

The step that matters

Cook slowly after adding the sugar. Sugar must dissolve fully and the mixture must reach a thick concentration to set into a gel. Cooking too hard or too long can scorch the sugar, darken the flavour and make the texture stiff.
