Ingredients
Method
- In a non-reactive pan, mash the blackberries with a potato masher.
- Add the sugar and heat the contents over medium heat, stirring gently, until the sugar is dissolved.
- Raise the heat to medium-high and boil the mixture for about 10 minutes. You want to do it long enough that a drop mounds in a chilled dish.
- Pour the jam into a jar and cap the jar tightly. Store in refrigerator. This jam should keep for several weeks.
