A very fine pizza can be made in an oven built from cob - clay, sand and straw mixed together. This can be hand formed into the domed shape around a solid base of fire bricks that absorb and maintain the heat needed to cook the pizza. These images show a course run for people interested in learning how to build for themselves. It was a fun day with a lot of muddy clothes and a lot of laughter. It was also much more physical than most people realised!
