What each ingredient does
- Raspberries
- Provide the fruit flavour, colour and pectin-bearing body that the jam is built around.
- Sugar
- Sweetens the jam and, with boiling, helps it thicken and set while keeping it preserved.
The step that matters
Boil for exactly 2 minutes from the first boil. Boiling concentrates the sugar and fruit so the jam can gel as it cools. Boiling too briefly leaves it runny, while overcooking can make it stiff and dull in flavour.
