It seems to keep its shape better in the dutch oven and it keeps it moist more so it gets chance to rise before the lid comes off for the crust. I think you can even do these in a fire pit, but I've never tried that before. I promise you sourdough is far easier than you think - go by intuition and feel. If you make bread, you get the premise of kneading and proving - this one is no knead although you do fold and knead it gently at the midpoint. Let me know how you go!!
