I can attest and confirm that this process really works. When I made my very first breads last week, I followed this process and the results were outstanding. Instead of thyme, I used Italian seasoning for that basil, and oregano flavor through out the loaf. It was really good. I toasted up some of the slices with pico de gallo (chopped tomato, onion, jalapeno pepper, lemon juice, salt and pepper) on top with a sprinkle of mozzarella cheese and it was good.
For a dutch oven, I used a cast iron deep skillet with a cast iron lid which I coat with olive oil. Works very nicely with an even browning all over.
Just follow PZ's directions. It is great!!!!
