Shared aroma: 2-nonenal (fatty, green).
Sugar and lemon 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
- Forms a network as it cools, turning the liquid into a firm, wobbly set.
- Sugar
- Adds sweetness that balances the sharpness of the lemon.
- Lemon juice
- Supplies the tart flavour and acidity that defines the jelly's taste.
The step that matters
Dissolve the gelatine completely in the boiling water. Gelatine only forms its network once it is fully hydrated and dispersed. Undissolved granules leave grainy specks and weaken the set, so the mixture should be clear before the sugar and lemon juice go in.
