    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

Isinglass
Gelling agent that lets the liquid set into a firm, wobbly jelly as it cools.
Orange juice
Provides the main flavour and a bright acidity that balances the sweetness.
Sugar
Adds sweetness and rounds out the tart flavour of the orange juice.

The step that matters

Dissolve the isinglass fully in the boiling water. Isinglass is a collagen-based gelatin. If it is not completely dissolved, undissolved bits stay as lumps and the jelly sets unevenly. Soaking it first helps it hydrate and dissolve smoothly in hot water.
