Avoid Runny Ricotta
Hot Tips for Cooking With Cheese From Food Network Kitchens' Katherine Alford:
Ricotta is high in moisture, so when it's baked on a crust (think calzones, pizza or savory pies), it can make the dough soggy. To prevent this, add a tablespoon or two of breadcrumbs to the ricotta filling, like Food Network Magazine did for these Three-Cheese Calzones (pictured above). The crumbs will absorb excess liquid from the cheese and keep the crust dry.
