Blackberry Jam Recipe for Water Bath Canning
Every start of summer our blackberry crop comes in and I spend every day for a few weeks picking and washing and freezing them. And every year I gather the large berries until I have enough to make this delicious jam. I grow these berries on my homemade fence trellis. Growing these blackberries is almost an addiction. I seem to extend my berry trellis more and more every year. They are so easy to grow and harvest your own blackberries every year.
Homesteaders cost to make this yummy canned jam recipe comes to roughly $10.65 for about 8 half pints of jam or $1.33 per half pint. We have two blackberry trellis filled with flowering vines every spring.
