In the summer, my family would go pick tons of blackberries and use them in our cooking.

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. Read More

First time making jam since helping my Grandmother 30 years ago and WOW! I did core the berries first by using a drinking straw. But other then that I stuck to the recipe and it turned out great. Read More

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! Read More

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. Read More

This was the easiest jam I have ever made and it was awesome. I had picked two pints of blackberries so I only could make half the recipe. I canned two half-pint jars with half the recipe. I did not use the Allspice b/c I didn't have any. I imagine Vanilla extract or Vanilla bean would be great added to this recipe as well. Read More

Loved this jam! It was my first jam and this was pretty easy. We used it for toppings for pancakes, cheesecake, toast and also for sandwiches. Next time, we will hold off on the allspice & cinnamon to try for a fresh, berry flavor. Delicious. Will use again and again. Read More

I made this as a topping for a blackberry pie. Very delicious! Make sure you keep stirring constantly though. Don't step away or you might burn the bottom of it because it thickens very quickly. Read More

My first time making jam..... Super easy.. Fast quick easy.. I also canned it after I was done. I made so far 2 batches and I have more to make. both batches was made with (Oregon) wild blackberries. *1st batch I omitted the all spice, ground cinnamon just because I wanted the plain 'ol fashion recipe style... Raised bees for the first time this year, about a week ago we got the honey soooo guess what *2nd batch in place of sugar I used honey (honey replacement value is equal 1/1) so 1 cup honey replaced the one cup sugar, I also used 3/4 teaspoon vanilla, I omitted the all spice so I used a little more ground cinnamon 3/4 teaspoon ground cinnamon. as for the cornstarch I used 2 1/2 tablespoons just because I used the honey instead of sugar..... IT TURNED OUT EXCELLENT LOVED IT WITH THE HONEY & VANILLA!!!! Give it a shot and tell me what you think... ENJOY! thank you for a great recipe. Wonderful to can. Read More
