Were you onboard with Kramerâs bake you own pizza thing? If indeed you were, then perhaps youâd also be interested in creating your very own backyard Pizza Oven. fritz.bogott on instructables has posted a DIY that gets you closer to cooking the old-fashioned way. A detailed step-by-step guide enables you to build a backyard oven. The builder says that some salvaged material and a couple of unemployed friends over a weekend would be all that takes to construct this Stone Age structure. Take a look at this thing and you would be quite impressed with the effort that has gone into the thing. And no less effort is needed for baking in this thing either. One must heat the oven for two hours and then undertake little mopping before pizza can be shoved inside. So go ahead and enjoy the wonderful DIY exercise if you can spare a little (read a lot) time. Or you could do the suave thing, splash some money around and get one of these.
