What each ingredient does

Oranges
Make up the fruit that is softened, then candied and preserved in the syrup.
Sugar
Forms the syrup that preserves the fruit and turns it clear and thick as it cooks.

The step that matters

Boil the oranges until a straw can pass through them. Peel and boil until the rind is fully softened before adding syrup. Undercooked peel stays tough and resists the sugar, so the fruit will not turn tender and translucent.
