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.

This was the very first time I have ever "canned" anything in my entire 53 years and, oh boy, did I pick a winner. DH & I got up at 4:30 in the morning to be at the farmer's market for 5:30 when they opened in the hopes they would have fresh-picked blackberries. One man had some and I bought everything he had. I had enough berries to make two batches and I came out with 7-8 Ounce jars from each batch and about 2 cups left over that I just put in the refrigerator because I knew we would eat it right away so there was no need to process it in jars in the water bath. I cooked biscuits this morning, slathered them with the jam and all you could hear from me and DH were moans of ecstasy with each bite of biscuit - the flavor was truly heavenly and a wonderful taste that I remember from childhood. The only thing I did different is after I finished cooking the berries I removed it from the stove and skimmed off the foam that had accumulated on the top and let it sit for a total of 5 minutes before adding to the sterilized jars (I read this in a "canning" book). Also, since this recipe does not give any instructions on how to prepare the jars and lids if you are novice or "first time canner" like me be sure to read the guidelines on how to properly prepare the jars and lids. After removing all the jars from the water bath hearing the "pinging" was truly music to my ears. This recipe was so easy and right on target - thanks Mizz Nezz!
