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
- Strawberries
- Provide the fruit flavour and the bulk of the preserves.
- Sugar
- Sweetens the fruit and, with the boil, helps the preserves thicken and keep.
- Lemon juice
- Adds acidity that brightens flavour and helps the pectin set.
The step that matters
Boiling with lemon juice. Once the lemon juice goes in, the mixture must reach and hold a full rolling boil for the stated time. Strawberries are low in natural pectin, so a proper boil with enough sugar and acid is what lets the preserves gel and keep safely.
