Bakery baguettes are made in special steam-injected ovens. It's part of what gives them their characteristic crackly, crisp crust.I am an avid reader and still had to go through it a few times. My brain fog is growing exponentially! Frankly, I got lost when you posted "stick a pan of boiling water in there". LOL
That can somewhat be duplicated by boiling some water, pouring that in a baking dish, and setting it on the bottom rack of the oven. It adds steam to the oven.
Then, every so often during the bake time, use a spray bottle to mist the baguettes and that adds more steam.
