Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Provides the gel structure that makes the jelly set firm when cooled.
- Sugar
- Adds sweetness and balances the sharpness of the lemon.
- Lemon juice
- Adds sharp acidity and bright lemon flavour.
- Grated lemon peel
- Adds concentrated lemon aroma from the oils in the peel.
The step that matters
Mix well after adding the boiling water. Gelatine only sets when it is fully dissolved. Undissolved granules leave weak, grainy spots in the finished jelly, so stir until no particles remain.
