M&S Italian Prosciutto & 3 Cheese Pizza Our 30 hour slow fermented dough is topped with our signature rich, slow-cooked sauce made with Italian tomatoes, basil, olive oil and garlic, topped with a luxurious blend of Italian provolone, Italian pecorino and mozzarella cheeses. Once cooked, finished with slices of our expertly-sourced aged Prosciutto, just like the Italians do. Oven cooks in 10 minutes. Serves 2. Our pizzas are made with a blend of Italian 00 flour and strong white pizza flour. Slow-fermented using a traditional process the Italian's call 'Biga', for a complex flavour, and wood fired in our Italian oven for the perfect texture.
