Making blackberry jam is a labor of love. When it's wild berry pick'in it's time to GO! My #1 rule is never pick a berry before it's time. It's just a waste of a soon to be good berry. I always remove 1/2 of the seeds. Another labor of love. My friends can't get enough of this wonderful jam. Their even willing to pay $5.00 per 8.0 oz jar. And with the labor that goes into this, it's worthy of every penny.
