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.

What each ingredient does
- Gelatine
- Sets the liquid into a firm, wobbly gel as it cools.
- Granulated sugar
- Adds sweetness and helps give the jelly a clean, tender set.
- Citric acid or lemon juice
- Adds tartness that balances the sweetness and brightens the flavour.
The step that matters
Dissolving the gelatine fully. Gelatine must be softened in cold water first, then dissolved in hot liquid. If undissolved granules remain, they will not set and can leave a grainy or lumpy texture in the finished jelly.
