Instructions
- Use a potato masher or pastry cutter and lightly smash the blackberries.
- Measure 3 1/2 cups of blackberries into a mixing bowl.

Notes
Makes 3 half-pints (8 oz).
If you are using frozen berries, allow them to sit out at room temperature for a few hours or overnight to thaw.
If you’re using glass jars, make sure you leave 1/2 inch of headspace when filling the jars. Headspace is the space between the top of the food and the top of the jar. You need to give the jam a bit of room to expand in the freezer.
You’ll need about 6 cups of blackberries to yield 3 1/2 cups of smashed berries.
A previous version of this recipe called for 1/4 cup of freezer jam pectin. After testing various brands of pectin, I found that some resulted in a runnier jam when using 1/4 cup.
