Gregg Wallace is in Italy, at an enormous pizza factory where they produce 400,000 frozen pizzas each day. He mixes up a 450 kilo batch of dough for the bases; enough for 180 000 pizzas. He watches as each one is stretched to exactly 26 centimetres in diameter, then pricked with 522 holes, each 4mm deep, before they’re topped with tomato and disappear into the wood fired oven. It’s 25 metres long and the floor is made of rotating panels of volcanic rock heated to 450 degrees Celsius. Gregg’s pizzas emerge fully cooked after just 80 seconds. They’re topped with cheese, pepperoni, chillies and onions, then frozen and dispatched on their 1000 mile journey to the freezer compartments of British supermarkets.
