I have 6 blackberry bushes in my yard.
Great recipe, but my family likes seedless jam.
I do one extra step, I strain the cooked down berries through a wire strainer and to get all the goodness out I push them through with a gravy ladle. Super simple and seedless.

My son LOVES blackberry jam, so I tried this out. It's GREAT! I did cheat and use frozen blackberries, but it was still wonderful.

If I had to write this review in a few words - it would be WOW! and Delicious! Oh and very easy to do. We are a bit new at canning and this recipe was easy to do. I love the fact that I don't have to buy manufactured jams anymore! Thanks for a keeper :)
