500g White Flour
Cup of Starter
650ml of warm water.
Mix, leave over night to form the sponge.
Next morning, add 25g of salt, 600g of either white/brown flour. It's a wet mix, so dust your hands with flour as well as the working surface and the dough!
Kneed the dough until it windows or tears (if it's brown) and let it rise for an hour or two, gently poke it until it deflates, then repeat 3/4 times. Leave in bowl until doubled in size.
Set the oven to as hot as possible and heat an oven tray. Take tray out, sprinkle with flour, dump dough onto it, slash as artistically as you like, put into oven with a pan of boiling water at the bottom. Turn temp down to 200'C and bake for 40+ minutes until cooked. Leave to cool before cutting!
