To Preserve Oranges
Ingredients
Directions
Prepare the rinds
Cut the rinds of the oranges into leaf shapes.
Scoop out the insides with a teaspoon.
Soak the rinds in cold water mixed with salt for 2 days, changing the water frequently.
Boil the rinds in plenty of cold water until they are tender.
Make the syrup
Clarify the sugar, using 1 pound for each orange.
Place the rinds in a pot.
Pour the syrup over them.
The next day, pour off the syrup.
Boil the syrup.
Repeat this process four times.
Add the strained juice of 4 bitter oranges and the rinds.

Jar and cover
Carefully place the rinds in jars.

What each ingredient does
- Bitter oranges
- Their peel provides the main structure and the characteristic bitter aroma of the preserve.
- Sugar
- Makes the syrup thick and sweet, and helps preserve the rinds by drawing out water.
- Juice of bitter oranges
- Adds acidity and bright citrus flavor that balances the sweetness of the syrup.
The step that matters
Boil the rinds in plenty of cold water until they are tender.. The rinds must soften fully before the sugar syrup is added. Boiling in fresh cold water helps reduce bitterness, and rinds left undercooked stay tough and chewy in the finished preserve.
