Were those chiles roasted in the DO? Looks like open flame to me, which will be unfair to those using pots only. Just checking.
Rules from SumOfMyBits:
1. Everything cooked has to be performed in the dutch oven. If you are cooking twice (finishing or beginning with a different cooking method) that too shall be performed in the dutch oven. Deep frying, baking, braising; all cooking methods must utilize the DO. If you need to flip the dutch oven's lid over to make a skillet to finish the piece, that works. Authenticity is key. Pretend this is your only piece of cookware, and let the imagination run wild. You may use condiments like hot sauce, salsa, guacamole, etc., that may be prepared on the side, but everything else must be made in the DO. Kudos if you make your own hot sauce in the DO!
