Put all the ingredients in a food processor with the hook attached (it’s better to put the salt last)
Start kneading at a very slow speed until everything is combined
Then knead on half speed for 15 minutes
Put the dough in a non metallic bowl and cover with cling film, let rest for 4 hours
old the dough over itself a few times and shape either in a ball or an oval (depending on the size of your cast iron pot)
Cover and let it rise for 1 hours (it won’t rise that much at this stage – see the picture)
After 30 minutes turn the oven on at 240 C with the cast iron pot inside so that it gets really hot
Put the dough in the hot pan, and cook with the lid on for 30 minutes
Remove the lid and let it cook for another 10 minutes
