Orange Marmalade
Ingredients
Directions
Prepare the fruit
Wash and dry the oranges, then grate off any discolored parts.
Cut the rind in half and loosen it with a spoon to remove each half entirely.
Remove the core and seeds, leaving the juice and pulp.
Place the skins in a saucepan with cold water and cover tightly with a cloth.
Boil for several hours until tender enough to pierce with a pin.
Drain the water and scoop out the soft part, leaving thin skins.
Cut the skins into thin strips, about half an inch long.
Make the marmalade
Clarify and boil the sugar until it reaches a high candy stage.
Add the peel strips.
After ten minutes, add the juice and pulp.
Boil all together until transparent.

What each ingredient does
- Bitter oranges
- Provide the peel, pulp and juice that give marmalade its bitter flavor and set.
- Fine loaf sugar
- Sweetens the marmalade and, once boiled, helps it set and keep.
The step that matters
Boil the peel until tender before adding sugar. Peel is tough and bitter. Cooking it long in water softens the fibers, so the strips become tender in the finished marmalade rather than chewy.
