- 2 cups fresh blueberries, rinsed and drained -
- ¾ to 1 cup sugar -
1. Place blueberries in a medium saucepan and cook over low heat, scraping down the sides of the pan occasionally with a wooden spoon.
2. Add sugar and stir constantly until sugar dissolves. Stop stirring once the blueberry mixture begins to boil and is slightly thickened, with a jam-like texture.
3. Test if mixture is ready by placing a clean spoon into it and then holding the spoon up sideways. If the juices stick to the spoon, or if they form a mound when you drop it, then you know the jam is ready.
4. Pour jam into warm jars and seal. Process if desired.
NOTE: A good guideline is to add ½ to 1 cup sugar for each cup of fruit, depending on desired sweetness. The more sugar you add, the thicker the jam will be.
