What each ingredient does
- Strawberries
- Provide the fruit base, flavor, and natural pectin that helps the jam thicken.
- Granulated sugar
- Sweetens the jam, helps it set into a gel, and preserves it.
The step that matters
Boil the mixture quickly for another 25 minutes. The sugar must be fully dissolved and the mixture must reach a hard, rolling boil so the pectin and sugar can form a gel. Too little boiling leaves the jam runny, while overcooking can darken and stiffen it.
