What each ingredient does
- Gelatine
- Forms the gel network that gives the jelly its firm, sliceable set.
- Sugar
- Adds sweetness and balances the sharpness of the citrus juice.
- Lemon rind and juice
- Provides acidity and bright citrus aroma that flavour the jelly.
The step that matters
Dissolve the gelatine in cold water first. Gelatine granules must hydrate in cold liquid before heating so they dissolve evenly. Adding them to hot liquid directly can cause clumps, and the gel may then set unevenly or grainy.
