What each ingredient does
- Raspberries
- Provide the fruit flavor, bulk and natural pectin that help the jam set.
- Granulated sugar
- Sweetens the jam and draws out juice, and helps it thicken and keep.
The step that matters
Boiling to the right consistency. Boiling drives off water and concentrates sugar and pectin so the jam sets. Stopping too early leaves it runny, while boiling too long can scorch it or make it stiff.
