What each ingredient does
- Isinglass
- Gelatin-like setting agent that gives the jelly its firm, sliceable body.
- Powdered sugar
- Draws juice out of the pineapple to form a sweet syrup.
- Fresh pineapple
- Provides the main fruit flavour and the syrup base for the jelly.
- Curacao
- Adds orange aroma and extra flavour to the finished jelly.
The step that matters
Carefully turn out the jelly when set. Isinglass sets to a fairly delicate gel, so it must be fully firm before unmolding, and a gentle release helps prevent tearing or collapse of the pineapple-shaped form.
