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.
