M&S Collection Italian Fennel Salami & Potato Pizza Lovingly named pizza bianca in Italy - our 30 hour slow fermented dough is hand-topped with a creamy mascarpone and bechamel sauce with deliciously spiced Italian fennel salami and gorgeously golden thyme tumbled potato slices. 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.
