Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Provides the structure that lets the liquid set into a firm jelly.
- Sugar
- Adds sweetness and balances the sharpness of the lemon.
- Lemon juice
- Adds acidity and sharp flavour that defines the jelly.
- Grated lemon peel
- Adds aromatic oils that give a stronger lemon fragrance.
The step that matters
Melting the gelatine completely. Gelatine only sets when its granules fully dissolve in the hot liquid. Undissolved granules leave specks and weak patches, so the mixture should be stirred until no grains remain before straining and pouring.
