What each ingredient does

Seville oranges
Provide the bitter peel and juice that give marmalade its characteristic flavour and set.
Clarified sugar
Sweetens the marmalade and, when boiled down, helps it set and keep.

The step that matters

Boil again until it hangs to the spoon. Setting depends on reaching the right concentration of sugar and pectin. Too short a boil leaves the marmalade runny, while overboiling can make it stiff and dark.
