I have several hobbies. Making things grow is not one of them. I was the only kid in my seventh-grade biology class who couldn't get a potato to sprout, and the money I earned looking after a neighbor's home one summer didn't cover the cost of replacing the house plants that had died under my care.
My luck with yeast is not much better, and although I can tolerate life without ficus trees and ferns, I'm not sure about life without homemade Calzone. The only thing to do was to come up with a good, chewy Calzone crust that doesn't call for yeast; this I did.
1 1/3 cups unbleached all-purpose flour
2/3 cup gluten flour
1/2 teaspoon baking powder
Sift together unbleached flour, gluten flour and baking powder in a large bowl. With wooden spoon, beat in 1/4 cup yogurt, adding more as you beat until dough is soft but pliable. Turn out onto lightly floured board and knead until smooth and springy. Wrap in wax paper and let rest for 1 hour.
