What each ingredient does

Isinglass
Sets the juice into a firm jelly as it cools.
China orange juice
Provides the main orange flavor and most of the liquid in the jelly.
Sugar
Sweetens the jelly and balances the acidity of the orange juice.

The step that matters

Skim without boiling. Boiling the mixture would cloud the jelly and can weaken the setting power of the isinglass, so the liquid should be kept below a boil while skimmed and stirred.
