Blackberry rhubarb jam tastes  like wild blackberries! The tartness of the rhubarb really intensifies the flavor of the blackberries! It's a taste of summer any time of the year!  8 ounce jar, homemade and  canned in small batches. This is always a favorite at the farmers market! Jam ( and all food on this site) is only available as PICK UP OR DELIVERY, I CAN NOT SHIP FOOD, as per Minnesota law / cottage food laws.These products are homemade and nit subject to state inspection.
