What each ingredient does
- Strawberries
- Provide the fruit, pectin and flavour that form the body of the jam.
- Granulated sugar
- Sweetens the jam and helps it set by binding water and thickening as it boils.
The step that matters
Boil the mixture quickly for 25 minutes. Boiling hard drives off water and concentrates the sugar and pectin until the jam reaches a set. A weak boil leaves it runny, and overcooking can make it stiff and dull in flavour.
