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, wobbly jelly as it cools.
- Lemon juice
- Provides the sharp acidity that defines the lemon flavour.
- Sugar
- Sweetens the lemonade and balances the tartness of the lemon juice.
- Lemon rinds
- Adds aromatic lemon oils that carry flavour beyond the juice alone.
The step that matters
Stir in the soaked gelatine until dissolved. Gelatine must fully dissolve in the hot liquid, or it will not set evenly and may leave gritty or rubbery spots in the finished jelly.
