Mine is an "out of the kitchen" utensil.

We discovered Dutch Oven cooking this Spring.
Not the same type of DO that has been listed by others on this thread.

Here is a link to some DO's in service on the Cabelas site:

This DO is for cooking outdoors with coal or over an open fire. We do the coal version.
The DO is cast iron and has three legs and a recessed lid to hold the upper coals. You put a specified number of coals under the DO and on the lid as per the recipe.
My husband is the main DO handler in our house. He loves it because he gets to wear a big pair of bright red suede gloves and use a special lid lifting tool. (He has a pic on his computer, I'll try to post it later)
Our favorite recipes are the fruit cobblers and crisps.
We have made pot roasts as well. We love making cobbler so much that we have been a bit lax on our recipe experimentation.
Plus, we need to expand our collection so that we can make chili, cornbread and dessert at the same time!

Next Fall we plan to attend "Dutchstream" in TN.
This is a combined Airstream and Dutch Oven rally.
Yes, the bikes will come too. Hubby cannot miss a chance to ride in the mountains and I should be ready for them by next Fall.
