This loaf can be baked in a 5 - 6 quart Dutch oven. Euro models may be marked with a "26" on the bottom of the pot or underside of the lid. I do not recommend using enamel coated cast iron for this recipe. Only use a cast iron pan that is rated and recommended for using directly on the grill.If you don’t have wheat flour on hand or prefer the flavor of white flour, you can make this loaf using all bread flour. Simply use 4 cups of bread flour and omit the wheat flour from your dough.
