David dives into the world of an Italian culinary treasure - buffalo milk cheeses, starting with a visit to a creamery in the town of Paestum where he meets the majestic buffalos face to face. David gets a taste of the luscious mozzarella di bufala - mozzarella made with buffalo milk, and the ricotta made with buffalo milk. David learns how to use buffalo mozzarella in several traditional seafood dishes and, with the help of his friend Carla, makes a scrumptious cheese dessert for a beach picnic in the beautiful town of Positano.
