Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the liquid into a firm, sliceable jelly as it cools.
- Sugar
- Adds sweetness that balances the sharpness of the lemon.
- Lemon juice
- Provides acidity and bright lemon flavour.
- Lemon rind
- Adds aromatic lemon oil for stronger citrus flavour.
The step that matters
Dissolve the soaked gelatin in boiling water. Gelatine must be fully dissolved, and the mixture kept from boiling after the gelatine is added, so it sets evenly. Undissolved granules leave grainy spots and weak patches in the finished jelly.
