Obange Marmalade
Ingredients
Directions
Prepare the peel
Wash and dry the oranges, then grate off any discolored parts.
Cut the rind in halves and loosen it with a spoon to remove the halves entirely.
Remove the core and seeds, leaving the juice and pulp.
Place the peel in a saucepan with plenty of cold water and cover with a cloth.
Boil for several hours until tender enough to be pierced with a pin.
Drain the water.
Scoop out the soft part, leaving thin skins.
Cut the skins into thin strips, about half an inch long.
Make the marmalade
Clarify the sugar.
Boil it to a candy height.
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 for texture and the juice and pulp for tartness and body.
- Fine loaf sugar
- Sweetens the marmalade and, once boiled, helps it set and turn transparent.
The step that matters
Boil the peel until tender before adding sugar. Peel is tough and must soften fully in long simmering; sugar hardens the peel's pectin and cellulose structure, so undercooked strips stay chewy in the finished marmalade.
