1. In a large bowl, combine the flour, yeast and baking powder.
2. Add the olive oil, water, salt (very little) and the rosemary that has been finely crushed in a mortar (or in a blender).
3. Mix everything again, adding a little more flour if necessary so that the dough does not stick.
4. Let rise for at least 3 hours near a radiator in a bowl covered with a plate.
5. Without disturbing the dough too much, transfer it to an oiled baking pan and gently oil the surface of the dough.
6. Place into a cold oven and heat to 250° C (500° F) for 25 to 30 minutes, depending on the desired doneness.
