For the roasted mushrooms
1. Before stretching and topping your dough, fire up your oven.
Aim for 400 to 450 °C on your pizza stone. You can check this quickly, accurately and from a safe distance with an infrared thermometer.
2. Slice any larger mushrooms you may have into nice thick pieces and halve any small ones, or feel free to leave them whole.
Place your cast-iron skillet into the oven to warm up for 10 minutes. (If it’s nice and hot, the mushrooms will cook quicker.) Using oven gloves, remove the hot skillet from the oven and scatter over the mushrooms. Drizzle 2 tablespoons (25 grams) of olive oil over the mushrooms, then add the garlic and thyme leaves. Season well with salt and pepper, mix the mushrooms around, then even them out.
3. Pop the pan back into the oven and roast the mushrooms for 2 to 3 minutes, turning them with a spatula once or twice as they cook.
When they’ve lost all their moisture and smell good, remove the mushrooms from the oven and set aside.
For the pizza
1. Place a dough ball on a lightly floured surface, flour your hands and use your fingertips to press it into a small, flat disc.
Working from the centre, push the dough outwards while spreading your fingers, making the disc bigger. Pick up the dough and gently pinch it around the edge, allowing gravity to pull it downwards into a circle with a 12-inch (30-centimetre) diameter.
2. Using a spoon, spread a bit more than 85 grams of the tomato sauce out evenly over the pizza, leaving about 1 inch (2.
5 centimetres) for the crust. Tear or cut over 62 grams of the mozzarella, then arrange 2 to 3 slices of pancetta on top.
3. Scatter over ¼ of the roasted mushrooms, then dot the top of the pizza with 50 grams of gorgonzola.
Season the pizza with a pinch of sea salt, a twist of black pepper and drizzle over a bit of olive oil.
4. Lightly flour your pizza peel, slide it under the pizza and launch it into the oven.
Cook for 60 to 90 seconds, turning it often to ensure an even bake.
5. Remove from the oven, slice, serve and enjoy! Repeat the steps with the remaining dough balls.
