M&S Collection Calabrian Pepperoni and 'Nduja Pizza Our 30 hour slow fermented dough uses the finest ingredients from our Italian suppliers and is generously topped with thickly sliced Calabrian pepperoni, rich and spicy Calabrian 'Nduja and creamy Italian mozzarella pearls. Drizzle with chilli-infused hot honey just before serving for a sweet, fiery finish. Oven cooks in 11 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.
