    Shared aroma: beta-damascenone (apple, rose).

Orange and sugar barely smell alike, yet cooks put them together in 19,212 recipes: they work on texture and structure more than aroma.

What each ingredient does

Small oranges
Provide the fruit, flavour and the main body of the jelly.
Sugar
Sweetens the jelly and helps the syrup become clear and thick.
Isinglass
Gelling agent that sets the liquid into a firm jelly.

The step that matters

Cook the fruit over low heat until clear. Gentle heat lets the sugar syrup penetrate the fruit slowly, so it turns clear and holds its shape. High heat can break the fruit apart and make the syrup cloudy.
