Quick Tips for Freezer Jamming
This recipe was tested with Ball and Sure-Jell brand pectins; look for either in the supermarketâ€™s baking aisle.
Always leave at least a 1/2-inch head space because the jam will expand as it freezes.
Make sure your fruit is ripe so the jam sets properly.
To crush fruit, chop flesh and mash with a potato masher.
This recipe also works well with berries. You'll need about 2 1/2 pounds of strawberries, blueberries, raspberries, or blackberries to make 5 cups of crushed fruit for berry jam.
