What each ingredient does
- Gelatine
- Forms the gel network that sets the liquid into a firm, wobbly texture.
- Sugar
- Adds sweetness and contributes to the smooth, soft body of the set dessert.
- Lemon juice
- Provides acidity that balances the sweetness and gives the dessert its bright flavour.
The step that matters
Soak the gelatine in cold water. Gelatine must hydrate in cold water before heating so its protein strands unfold evenly. Adding it dry or to hot liquid can leave lumps and weaken the set.
