Lemon and sugar barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
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 balances the sweetness of the jelly.
- Sugar
- Sweetens the jelly and adds body to the set texture.
- Lemon rinds
- Adds aromatic lemon oils that flavour the jelly.
The step that matters
Dissolve the gelatine fully before adding other ingredients. Gelatine only sets properly when it is completely dissolved and evenly distributed. Undissolved granules leave weak or grainy patches in the finished jelly.
