3 cups all-purpose flour
1-3/4 tsp. salt
1/2 tsp. active dry yeast
1-1/2 cups room temperature water
Mix the flour, salt, yeast in a large bowl. Add herbs or cheese if desired. Add the water and mix until the mixture has just pulled together. It will be sticky. Cover the bowl with plastic wrap and set on the counter for 12-24 hours.
When ready to bake, place a cast-iron or other oven-safe pot (with a lid) in the oven and preheat to 450 degrees. Flour your work surface and hands and form the dough into a rough ball. Take the pot out of the oven. Drop the ball of dough into the pot. Cover and bake (with the lid on) for 30 minutes. Take the lid off and bake for another 15-20 minutes to allow the bread to brown. Let cool almost completely prior to slicing.
