Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Forms a protein network that sets the liquid into a firm jelly.
- Lemon juice
- Adds sharp acidity and bright lemon flavour.
- Sugar
- Adds sweetness and balances the lemon's sharpness.
The step that matters
Stir well and strain into moulds. The gelatine must be fully dissolved in the hot liquid before it is poured. Undissolved granules or lumps will not set evenly, leaving a weak or cloudy jelly.
