I turn the oven on as high as it goes and put the steel in and prep all the pizza toppings, then I switch the oven to the grill mode (or broiler in the US) then make the pizzas. It takes about 5 mins per pizza, so it’s a bit slower than the pizza oven but I can make the next pizza while the first is cooking so it’s fine.
My family say they prefer this to pizza made in the Ooni, I think they are both on par with each other but this is less hassle, cheaper than running the Ooni and less stressful because things don’t catch fire as fast.
Seriously, is it really supposedly that much better than my £15 cast iron 'stone'? (I put a lovely seasoning on it initially, but didn't look after it very well and it's all cracked and flaking off, so I need to start again really I think - I suppose it does save that maintenance work... but still, I could just buy a new one and start again several times for $120!)
edit: the issue is they only sell 'wholesale' quantities. 20' sticks, 4'x8' sheets
