Library book "Bread Illustrated" by America's Test Kitchen. I thought I'd give the calzone recipe a try mainly to see the dough. I was pretty happy with the dough and would try it again. The filling they used was just OK for me. Spinach, mozzarella, ricotta and parmesan. Little garlic also. I find the parmesan a little to mild and would try romano if I did it again. The dough I would use again, and I'm thinking brocolli rabi and sausage with a little seasoning. Plenty of fillings to try.
