Notes
Special equipment needed: 12 foil cupcake liners.Camp Cooking Tip: To ensure even baking in your Dutch oven camping recipes, rotate the camp oven throughout the cooking time so everything cooks evenly. 1/4 turn for the bottom (say clockwise) then 1/4 turn in the opposite direction for the lid (this would be counterclockwise.) I like using a lid-lifter for this process but you can also use heat-resistant gloves or another favorite flameproof tool.Camp Cooking Tip: If muffins are done but not browned, move some of the charcoal briquettes from the bottom of the oven to the top of the oven and continue baking until the muffins are golden.Here are a few more useful links:Dutch Oven Temperature Charthttps://www.campingforfoodies.com/dutch-oven-temperature-chart/Camping For Foodies Recipes Listhttps://www.campingforfoodies.com/camping-recipes-list/Our Productshttps://www.campingforfoodies.com/shop/
