    I had to use Walmart brand FROZEN unsweetened blackberries only because I haven't been able to find fresh blackberry bushes here. I just let them partially thaw out before using them. Other than that, I kept to the recipe. This firmed up perfectly and had the right amount of sweetness with a hint of spice. This is one of the best blackberry jams I've had yet! Next time, I'll try this without the spices (even though I liked it, the family did not). Either way, I bet good money that it will turn out fantastic every time.  -  30 Sep 2012  (Review from Allrecipes US | Canada)


    This is the BEST jam I've ever had. It has so much flavor and not too sweet. I didn't use the cinnamon and allspice, I just wanted the basics and it turned out great! I also used this jam in a cobbler recipe and it turned out great too. Enjoy!  -  29 Jul 2012  (Review from Allrecipes US | Canada)


    This makes excellent jam! I've only ever made jelly/jam with pectin, so I admit I was a little nervous at first not putting it in. However, the cornstarch thickened it up nicely and the pectin wasn't necessary at all! The only thing I changed was I left out the allspice because I didn't have any.  -  08 Jul 2012  (Review from Allrecipes US | Canada)
