I just purchased a 6 QT Dutch Oven yesterday. I have never used a DO befor, but have seen it referenced several times on the forum. I currently have a Large and a Small Egg. What sizes are usually used for these? Also, do you use them very often? I can see uses for stew, or chili, but don't know what else they'd be used for. I look forward to hearing your responses. Thanks in advance.
