What each ingredient does
- Strawberries
- Supply the fruit, flavor, color and body of the jam.
- Sugar
- Sweetens the jam, helps it set, and helps preserve it.
The step that matters
Boil the mixture for about 20 minutes. Boiling evaporates water and concentrates the sugar and fruit. Enough cooking lets the pectin form a gel as the jam cools. Undercooked jam stays runny, while overcooking can darken and scorch it.
