What each ingredient does
- Strawberries
- Provide the fruit flavor, bulk and natural pectin that help the jam thicken and set.
- Granulated sugar
- Sweetens the jam and helps it set by binding water and thickening as it cooks.
The step that matters
Cook to 218°F (103°C). Jam sets as its sugar concentration and temperature rise together. Stopping short leaves a runny jam, while cooking too long makes it stiff and dense.
