Calzones are the natural evolution of the pizza. The same white bread dough is used but instead of being baked flat the dough is folded over a filling, like a Cornish pasty.
Calzones can be filled with any of the topping mixtures suggested for pizzas but remember the filling must not be too wet initially. Be careful not to overfill the calzone or it may burst during cooking. Set the dough aside to rise before adding the filling.
