Orange Marmalade
Ingredients
Directions
Prepare
Grate the outer rind of the oranges into a dish.
Peel the inner rind and boil until tender.
Slice the inner rind like citron.
Separate the inner tissue and seeds from the pulp.
Weigh the pulp and inner rind, then use an equal amount of loaf sugar.
Wash the seeds and inner tissue, saving the water.
Make the marmalade
Dissolve the sugar in the saved water.
Add the pulp and sliced rind to the sugar mixture.
Boil for one hour.

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.
