What each ingredient does
- Sugar
- Draws moisture out of the strawberries and provides sweetness, helping set the jam as it thickens.
- Strawberries
- Provide the fruit flavour, natural pectin and body that give the jam its texture.
The step that matters
Boil the mixture for 20 minutes. Boiling evaporates water and concentrates the sugar and fruit pectin so the jam thickens and sets. Too short a boil leaves it runny; too long can darken and over-thicken it.
