invest in a pizza stone and do not wash in soapy water Semolina flour helps to stop the dough from sticking and adds extra flavour to the dough as well. If you do not have a pizza oven get your oven as hot as you can around the 300 mark is best. I remove the pizza from the pizza tin to crisp up on the pizza stone only for a minute as the stone is very hot and will burn the crust if left unattended. Cleaning Wipe the stone with a wet cloth my tip is the blacker the stone the better the flavours become. washing in soap will make the stone absord the soap . The sauce can be made prior and allow it to reduce to a nice paste, will keep in fridge for 2 weeks or more. Honestly how good is Australian food?
