Guys create their own Pizza Oven in their Backyard! An oil drum (barrel) and a bit of metal pipe is all you need to make a really simple but effective pizza oven. It may not look very fancy but it works well and it will cook a whole lot of pizza. Also, instead of waiting for days/weeks for your clay oven to dry enough to use, an earth oven can be made and used on the same day. Which is really handy if you have a few people coming round.
