Dutch Oven Temperature Chart
When recipes call for a specific temperature, use the following guide to determine how many coals you should use. To achieve the desired temperature, determine the size of your Dutch oven and find the corresponding "formula" for charcoal briquettes. For example, to reach 350 in a 12 inch Dutch oven, you should use 17 coals on the bottom and 8 on top. Easy as that!
When a chart is not handy, double the number on the oven lid (when present) for a basic number of charcoal briquettes to reach a Moderate oven temperature. Then apply the “ratio” top to bottom coals—for baking 2/3 of coals on lid, 1/3 of coals below oven. Example: If the lid says 12, use 24 coals. 8 on the bottom, 16 on top.
