What each ingredient does
- Gelatine
- Forms the firm, wobbly set as it cools after dissolving in hot liquid.
- Lemon juice
- Adds sharp acidity that balances the sugar and gives the jelly its lemon flavour.
- Sugar
- Adds sweetness that balances the lemon's tartness and adds body to the liquid.
The step that matters
Stir in the lemon juice and sugar until dissolved. Undissolved sugar or gelatine leaves grains and an uneven set. Stirring until fully dissolved gives a clear, smooth jelly that sets evenly as it cools.
