What each ingredient does
- Strawberries
- Provide the fruit bulk, flavor, and natural pectin that help the jam set.
- Granulated sugar
- Draws juice out of the berries, sweetens, and helps the jam thicken and preserve.
The step that matters
Boil very slowly for 30 minutes. Sugar and fruit must reach a gel-setting concentration without over-darkening or scorching. A gentle simmer lets water evaporate evenly while the pectin and sugar set properly, so the jam neither stays runny nor turns caramelized and bitter.
