Blackberry Freezer Jam
4 cups of blackberries mashed
1 1/2 cups of sugar or sugar substitute
1 envelope of freezer jam fruit pectin (1.59 oz)
First measure out 4 cups of fruit and mash with a potato masher. (another recipe I saw had you put the berries (they were using fresh strawberries) in a 9x13 pan but these berries didn't need much mashing so I just used a bowl.
Next you mix the fruit pectin and 1 1/2 cups of sugar in a bowl and add that to the berries. Stir for 3 minutes. I bought the fruit pectin at Winco it wasn't very expensive. I've also seen it at Walmart and Safeway. with the canning items. at Winco it is down the baking isle.
Finally ladel jam into jars or freezer containers to the fill line (or leave some space in a jar) and twist on lids. Let stand until thickened, about 30 minutes
makes about 5 (8 oz.) half pints.
