MC 5 Haven’t had chance to use it yet but I bought 2 as an alternative to a larger and much more expensive ‘baking steel’ available only abroad.Baking steel is effective for creating the right temperatures to cook authentic homemade pizza from scratch.I think a larger size of about A3/B4 would be effective for cooking pizza. The price is great, even if it doesn’t work it can be used on the bbq or gas burner. Let’s hope it’s effective for cooking pizza.
