Stir all the dry ingredients together in a large bowl before pouring in the water and oil.
Mix your ingredients with a spatula or whisk. Don't worry about the very wet shaggy mess in front of you, it will work.
Cover your bowl and leave for 3 hours at room temperature for the magic to happen. Alternatively, leave overnight (or up to 48 hours) in the fridge.
If your dough has been in the fridge, bring it out for a couple of hours to reach room temperature.
Sprinkle flour onto a work surface and scrape out the dough.
Shape the dough by pulling edges into the centre to form a ball. Pinch and rotate until it makes a tighter ball.
Flip it over and tighten a bit more by pulling towards you and rotating. Place on crumpled baking parchment and cover for half an hour.
Put your Dutch Oven or Le Creuset in the oven and preheat to 240°C / 220°C fan / 475 °F / 425 °F fan for 30 mins.
Carefully take out the very hot Dutch Oven and remove the lid. (Be careful where you place the “counter top burning” lid)
Lift the dough using the edges of the parchment and place into the Dutch Oven. Score across the top of your dough.
Replace the Dutch Oven lid and bake at 220°C / 200°C fan / 425 °F / 400 °F fan for 30 minutes.
Remove the Dutch Oven lid and bake for a further 15 to 20 minutes until golden brown.
Carefully lift your baked loaf from the Dutch Oven, again using the baking parchment, and allow to cool.
