Boil the raspberries over a brisk fire for 25 minutes, stirring occasionally.
Add sugar and set
Add the sugar and stir until dissolved.
Boil the mixture quickly for 10 minutes, stirring and skimming as needed.
For a richer jam, use equal weight of sugar and boil for 20 minutes.

What each ingredient does
- Raspberries
- Provide the fruit flavor, pectin and bulk that give the jam its body.
- Granulated sugar
- Sweetens the jam and, while boiling, helps it thicken and set and preserves it.
The step that matters
Boil the mixture quickly after adding the sugar. Sugar must dissolve fully before a hard, rapid boil so the jam reaches the concentration needed to set. Stirring and skimming keep it from scorching and clear off foam, which keeps the jam clean and well set.
