1To make the pizza dough, place the flour, semolina, salt and yeast in the bowl of a stand mixer. Using the dough hook, mix to combine. Add the water and oil and knead on low speed for 5 minutes, or until the dough is smooth and elastic.
2Cover the bowl with plastic wrap and allow to proof in a warm, draft-free place for 2 hours, or until doubled in size.
3Turn the dough out onto a lightly floured bench top and divide into 4 even pieces, approximately 5 oz each. Shape each piece into a smooth ball.
4Sprinkle a board, proofing box or deep sided container with semolina. Add the dough balls, leaving 4-inches between them. Cover with plastic wrap and proof in a warm, draft-free place for 30 minutes. Meanwhile, make the pizza sauce.
Tip: Alternatively you can refrigerate for at least 6 hours or up to 5 days. Remove from the fridge 1 hour before cooking to bring the dough to room temperature.
5To make the pizza sauce, place the tomatoes, oil, garlic, oregano, salt and chilli flakes (if using), in a large jug. Process with an immersion blender until smooth.
6About 15 minutes before the dough has finished resting, preheat the oven. Select the Thin & Crispy setting. Turn the Darkness dial to the Lighter setting and select 7 minutes on the Timer dial.
7Once preheated, sprinkle semolina on the bench top. Place one of the dough balls on the bench top and sprinkle with semolina. Keep the remaining dough covered to prevent it from drying out. Using a rolling pin, roll out one portion of the dough into a 10-inch round. Lightly sprinkle the pizza peel with semolina. Carefully transfer the dough onto the pizza peel.
8For each pizza, leaving a small border, spread 2 fl oz of the pizza sauce evenly over the dough. Scatter with ¾ oz mozzarella, then top with a quarter of the pepperoni slices. Finish with another ¾ oz mozzarella and a quarter of the parmesan.
Tip: The excess sauce can be refrigerated in an airtight container for up to 3 days. It can be used on pasta or wherever passata/tomato puree is used.
9Place the pizza in the oven, press the Timer dial and cook for 7 minutes, or until the crust is crisp, golden and the cheese has melted.
