Not sure if your question was to Bob or myself Livo, but for the crusty rolls I posted yesterday I used a pair of steelite dessert bowls, preheated in the oven, then dropped the dough into one and covered with the other, inverted so as to form an enclosed container. This is in place of the Dutch oven from the method in the video from the OP. It seemed to work nicely and I believe the theory is to form a steam chamber and heat store in one. My rolls had ten mins covered and 8 mins uncovered to brown, all at 210C in a fan oven.
Trying a larger one today (loaf) which is proving at the moment.
