I bought a flat of blueberries and four pints of blackberries at the farmer’s market in the morning and had most of them canned into jam by late afternoon. That’s what I call productivity. And delicious. I essentially made a batch of blueberry jam and a batch of blackberry jam together. Blackberries are a little sour so generally they require a bit more sugar so I just used the proportions off the pectin box for a batch of blackberries and for a batch of blueberries and put them all in one pot. These two berries are such a good combination of flavors. Katie seems to like it at least.
