A calzone has many of the perks of pizza. Easy and crowd pleasing, it’s a good vehicle for using up odds and ends in the fridge. It also has some happy benefits of its own. For one, you can get away with adding a lot more cheese. In fact, it’s practically mandatory. You need to stuff enough ricotta and mozzarella into the dough so that it ripples attractively, rising as it bakes. Unlike an apple turnover, which wants to stay flat, a calzone should peak and singe at the top. (True, you could cram the dough full of vegetables and the like, but if you love cheese, calzones are the place to indulge.) Another calzone advantage is the element of surprise. Pizza gives it all up as soon as it lands on the table; serve a calzone to a group and let them anticipate the moment when they find out what’s inside.
