Forgive the delay between stage 4 and 5, it is oh so tempting to put your feet up once you’ve made a basic earth oven. You can cook a most mouthwatering pizza in it, so you can get lazy, putting off the insulation layer. But if you attempt to cook pizza for the masses, your first pizza and maybe your second will cook like a dream in under 5 minutes, but by the time you get to your fourth or fifth the oven cools and you start getting nasty doughy uncooked centres.

Time for the next stage! Let’s make an eski out of this mudpie!

STEP 11: MIX IT MAKE IT

Make a sludgy mix of equal parts clay and sawdust and add water until you get that nice mudpie consistency, use a shovel to chop up any clay lumps. Apply it just as you did in stage 3, no need to pack it down too hard, you want all those air pockets made by the sawdust to trap the heat inside.

STEP 12: FIRE IT BAKE IT

Then all that’s left is to light a fire to dry it out and once it’s hot enough, why not push the burning embers to side and cook a delicious wood fire pizza!? There is nothing like it! Although warning once you try it you might become a pizza snob and those second-rate takeaway ones will never do! Perhaps a good thing for the health and the hips!

STEP 13: DO IT DOOR IT

Of course if you want to get into sourdough bread baking you’ll need a door. Pizza’s cook merrily fast in a super hot oven with the door off, but bread needs too cook more slowly and evenly so you’ll need a door. The bright sparks among you would have made the door first and then built the oven around it so it fits like a dream, but that’s not how we roll here. We just grabbed some timber off-cuts and banged them together then carved it to fit. Hey, it does the job! The bread needs a cooler over so remove all the fire embers before you bake it, once the dough is in shut the door and return in 15 minutes for a mouth watering delight! But don’t be too greedy let it cool a bit first, it’s still cooking once you take it out!
