Homemade Blackberry Jam
Ingredients
- 4 cups fresh blackberries
- 2 cups Swerve confectioner’s sweetener
- ¼ cup lemon juice
- ¼ teaspoon pectin
Instructions
- Combine ingredients: In a large saucepan, combine the blackberries, sugar, lemon juice, and pectin.
- Bring to a boil: Bring the mixture to a boil over high heat, stirring constantly.
- Simmer: Reduce heat to low and simmer for 10-15 minutes, or until the jam thickens.
- Test for set: To test if the jam is set, drop a small amount onto a chilled plate. If it doesn't spread, it's ready.
- Water-bath canning: Place the filled jars in a large pot and add enough hot water to cover them by 1 inch. Bring the water to a boil, then reduce heat to a simmer. Simmer for 20 minutes for half-pint jars or 30 minutes for pint jars.
- Remove and cool: Remove the jars from the water bath and let them cool completely before storing.
