Orange Marmalade
Ingredients
Directions
Prepare the peel
Peel the oranges and cut the peel into thin shreds, then into inch pieces.
Boil the shreds for 1 hour to remove the bitter taste, then drain and discard the water.
Cook and jar
Cut the oranges, saving all juice and pulp, but discard the seeds and white skins.
In a preserving kettle, combine the pulp, juice, shreds, and sugar, and stir until it boils.
Let it boil for 1 hour, skim off any foam, then pour into jars.
Once cool, cover with paper and store.

What each ingredient does
- Bitter oranges
- Supply the peel, juice and pulp, which give the marmalade its bitter flavor and natural setting power.
- Sugar
- Adds sweetness and, with long boiling, thickens the mixture and helps it set and keep.
The step that matters
Boil the peel before combining. Boiling the shreds in fresh water and then discarding it draws out much of the bitterness. Skipping or shortening this step leaves the finished marmalade harshly bitter.
