What each ingredient does

Bitter oranges
Supply the rind, pulp and seeds that give the marmalade its bitter flavour and natural pectin for setting.
Loaf sugar
Sweetens the marmalade, balances the bitterness and helps it set into a gel as it cooks.

The step that matters

Boil for one hour. The long boil concentrates the sugar and draws pectin out of the rind, pulp and seeds. Too short a boil can leave the marmalade runny, while overcooking can make it stiff and dark.
