The berry best freezer jam, ever! Strawberries, raspberries and blackberries combo. Courtesy Ball Blue Book of Preserving.
Combine crushed strawberries, raspberries, blackberries and sugar in a medium bowl. (I use a potato masher to crush the berries, you can leave some whole).
Let stand 15 minutes.
Gradually stir freezer jam pectin into fruit mixture.
Stir 3 minutes; let stand 5 minutes.
Ladle jam into can-or-freeze jars, leaving 1/2-inch headspace.
Adjust two-piece caps, label and freeze.
Tip: Will keep for several weeks in the fridge, or up to one year in the freezer.
