Shared aroma: 2-nonenal (fatty, green).
Lemon and sugar 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
- Watermelon rind
- Forms the bulk of the pickle and absorbs the syrup as it cooks.
- Sugar
- Sweetens the pickle and, as it cooks down, thickens the syrup.
- Lemons
- Add acidity that brightens the sweetness and balances the flavor.
The step that matters
Cooking until the mixture thickens. Sugar must dissolve fully and the syrup must reduce enough to thicken. Stopping too early leaves a thin, watery syrup, while cooking too long can make the rind tough and sugary.
