I've been making provolone with my mozzarella. I use the recipes that call for thermophilic culture and no citric acid. I just dry it for a few days at room temp and either wrap it in plastic wrap or wax (to age longer). It is very yummy after a couple of weeks wrapped in plastic and aged in my regular fridge. It think it was Tea that tried this and I thought it just marvelous. I've been doing it ever since! Check out her posts under the Pasta Filata section of the boards.
