Many foodies confuse the Philly Stromboli with the Italian Calzone. They have certain similar attributes yet are different in shape and filling. Stromboli is rolled up into a log shape while the calzone is folded and sealed into a half-moon shape. Furthermore, Stromboli’s filing includes low-moisture mozzarella cheese and tomato sauce. Contrarily, calzone has ricotta cheese with the sauce served on the side instead of filled in.
