What each ingredient does
- Gelatine
- Sets the liquid into a firm, sliceable jelly as it cools.
- Sugar
- Adds sweetness and balances the sharpness of the lemon.
- Lemons
- Provide the tart citrus flavour and aroma.
The step that matters
Soaking the gelatine in cold water. Gelatine granules must hydrate fully in cold water before heating; adding them dry or to hot liquid can leave lumps and weaken the set. Soaking first lets the granules swell evenly so they dissolve smoothly into the hot mixture.
