What each ingredient does
- Strawberries
- Provide the fruit body, pectin, and flavour that form the jam.
- Loaf sugar
- Sweetens the jam and helps it set by binding water and drawing out pectin.
The step that matters
Boiling for 20 minutes. Boiling drives off water and concentrates sugar and pectin so the jam can gel. Too short a boil leaves it runny, while over-boiling can darken the colour and dull the fresh fruit flavour.
