- Put everything in a bowl, and mix it until it's consistent. Usually takes 2-ish minutes. I find a simple, non-sharp knife to work best. - Cover it with cloth and let it sit for 12-20 hours depending on the mixture and temperature. - Get the mixture out, en cover with flower on all sides. Don't knead or overly touch (it will lose volume). - Preheat the oven with an iron cast over pot, once it's hot (250C), take out the pot, put in the mixture, and put on the lid. Halfway into the baking time, take off the lid.
