What each ingredient does
- Strawberries
- Provide the fruit flavor, bulk and natural pectin that help the jam thicken as it cooks.
- Powdered sugar
- Draws moisture out of the strawberries and sweetens, helping set the jam and preserve it.
The step that matters
Boil the mixture slowly for 30 minutes. Slow boiling lets water evaporate gradually so the fruit and sugar concentrate and thicken without scorching. Boiling too fast or too briefly can leave the jam runny or cause it to burn on the bottom of the pot.
