All dutch oven cooking is done by hot coals-- never in a flaming fire. The coals may be
from hardwoods like oak and hickory or from charcoal. Hardwoods yield long-burning coals
which are necessary for the lengthy cooking process in most dutch oven recipes. Soft woods
like pine are unsatisfactory.
In some respects, charcoal is more convenient to use and is necessary in areas where there
is no downed hardwood. Either lump charcoal or briquettes may be used, but the briquettes
are preferred for long-lasting fires. They give an even heat for long periods.
The amount of charcoal needed varies somewhat, depending on wind conditions, air
temperature, and the altitude. Obviously, a strong wind will cause the coals to burn
faster and become hotter. At high altitude, more coals will be needed because of the
thinness of the air. You'll also need more coals on a cold winter day than in the heat of
summer.
The following chart will give beginning dutch oven cooks a fairly accurate starting point
for the amount of charcoal birquettes needed for various temperatures.
This chart was developed to give the beginner a fairly accurate starting poing with
charcoal fuel. Temperatures will vary some due to the charcoal quality, wind, and other
weather elements.

Preheating Oven
It's important to preheat both the oven and the lid before starting to cook. Put the oven
on the coals separate from the lid. Put the lid directly on the coals, too, not on the
oven part. When you think it's heated about right, check it out using the flour test.
How do you know if the preheated temperature of your Dutch oven conforms to recipe
instructions such as "bake in a slow oven," or "Preheated to 375
degrees?"
Put a teaspoon of flour on a pan or plate that will fit in the oven. The color of the
flour after baking with the lid in place will give you a pretty accurate measurement.
| Light tan | in 5 minutes | Slow oven | About 250 degrees |
| Medium tan | in 5 minutes | Moderate | About 350 degrees |
| Dark brown | in 5 minutes | Hot | About 450 degrees |
| Dark brown | in 3 minutes | Very hot | About 550 degrees |
You regulate the heat by adding or removing some hot coals. The tendency is usually to get
the oven too hot, especially on the bottom. Remember, most cooking in a Dutch oven is from
the heat gained from the coals on the lid. For short cooking times you probably won't even
have to put coals under the preheated oven. Just put a few on the top. For longer cooking
time, take a few live coals from your fire supply, put them in a small circle, and set the
oven directly over them.
It's handy to have a small trench shovel to use in moving hot live coals around.
If your fire gets too hot, you can temper it by sprinkling a few drops of water on the
coals. If you are using charcoal, douse the coals with water after you have finished
cooking. Let the sun dry out the remaining charcoal to be used another time.
You can check cooking progress during cooking by sneaking a peak now and then. Lift the
lid quickly with a hook or tongs, but don't look long or you'll loose valuable heat from
the oven.
