I love cobblers! I ate one amazing awesome Blackberry cobbler in Pt. Townsend, WA years ago when visiting friends. These beautiful huge blackberries grow on bushes all over the town. One evening we went to this lovely restaurant and I had their home grown cobbler, I was a devotee from that moment on. Here's another berry cobbler made from frozen berries. Expect the fruit to be a bit waterier because of the moisture in the dish. If you want you can up the amount of tapioca or add a tbsp. of arrow root flower to the dish as well.
