Dutch oven outdoor cooking provides the opportunity to cook a wide variety of foods. Dutch ovens are extremely versatile, and can be used for virtually every cooking need. Dutch ovens can be used to boil, steam, fry, and bake, among other things. They can be used to cook meat, soups, breads, desserts, and to create hot drinks. With enough dutch ovens, you can create a multi-course, gourmet meal.
Dutch oven outdoor cooking requires coals. These can come from wood or charcoal. Charcoal is probably a bit easier to use, since they will burn and heat more evenly. Nevertheless, the smoke from the coals of a real fire can add some great flavoring to your dishes. There is nothing like food cooked over a fire.
Dutch ovens may be used on the coals in a fire, or they may be stacked, one on top of another, with coals on the lid of one dutch oven, heating to the bottom of the dutch oven above. You will sometimes see stacks of ovens using this technique. This is handy when fire space is limited, but may require a few more coals to keep the heat going.
Cooking with dutch ovens is lots of fun!
