Those clay pots are beautiful! I use a versatile and inexpensive Lodge “combo cooker” cast iron for baking. Versatile because it’s a top and bottom (couldn’t resist?).
For baking I preheat it, use the shallower lid on the bottom and the deep lid on the top (upside down vs, this pic below). But then for other cooking you basically have a cast iron skillet, and a pot as well. I have two, love them!
