00 flour is finer than plain flour, making it perfect for pizza dough. You’ll find it at supermarkets.
For crisp crusts every time, move the oven rack to the second-lowest rung. Place a pizza stone on the rack, then heat the oven to 220°C and leave stone to heat for 20 minutes. If you’re using a baking tray, heat it in the oven for only 10 minutes. Remove stone or tray from the oven and set pizza on top. Bake pizza for 15 minutes, or until crust is golden brown.
