Autolyse. Combine the flour, water, sugar, and starter in a large bowl and stir well. Use your hands to incorporate any dry bits. Cover with a clean, damp tea towel and let it rest at room temperature for 30 minutes.
Stretch and fold during warm rise. After the rest period, add the salt, dried cranberries, and orange zest. Knead for a minute or two until everything is thoroughly mixed in. Cover with a damp towel and let it rise in a warm place for three hours, reshaping the dough into a ball once per hour.
Second proof in the fridge. Heavily dust a banneton with rice flour. Shape the dough into a ball and place it in the banneton. Cover with plastic wrap and let it proof overnight in the fridge.
Prepare for baking. In the morning, preheat the oven to 450°F (230°C) with the Dutch oven inside. Remove the dough from the fridge and turn it out onto a sheet of parchment paper, aiming for the center. Slash the top with a lame or a very sharp knife. Carefully remove the hot Dutch oven and place the parchment and dough inside. Replace the lid.
Bake. Bake for a total of 55 minutes: 25 minutes covered, 25 minutes uncovered, and then 5 minutes directly on the oven rack to brown the crust. The bread is done when the internal temperature reaches 200-210°F (93-99°C).
Cool. Remove the bread from the Dutch oven and discard the parchment paper. Allow it to cool on a wire rack for 3 to 4 hours before slicing. Store at room temperature, tightly wrapped, for up to two days. For longer storage, freeze.
