Add flours, salt, and yeast to a large bowl. Stir to combine. Add water and gently mix until dough forms. Add nuts and fruit and fold in with your hands.

Transfer to a clean, greased bowl. Cover with a damp cloth or plastic wrap. Let sit at room temperature to rise overnight or at least 8 hours.

Once the first rise is done, turn dough onto counter and form into round loaf. Line a dutch oven or round casserole dish with a lid with parchment paper. Grease parchment paper and lay dough in the center stretch to line the bottom of the dish. Cover with lid and let rise again for 2 more hours.

Once second rise is done, score the bread with three stripes using a sharp knife. Place in cold oven and turn oven to 450 degrees. Bake for 45 minutes.

After 45 minutes of baking, remove lid from dish and bake for another 5 to 15 minutes, depending how brown you want the loaf.

Remove dish from oven. Carefully remove parchment from dish and let it cool completely on wire rack.
