1. 1. Combine Wet Ingredients and Starter: In a large mixing bowl, gently whisk together the active sourdough starter, warm water, fresh orange juice, and optional honey or maple syrup until well combined. The mixture should look milky and slightly frothy.

2. 2. Add Dry Ingredients: Gradually add the all-purpose flour and salt to the wet mixture. Mix with a wooden spoon or your hands until a shaggy, cohesive dough forms. Make sure there are no dry pockets of flour.

3. 3. Incorporate Cranberries and Orange Zest: Turn the dough out onto a lightly floured surface. Gently fold in the dried cranberries and orange zest, kneading lightly for about 2-3 minutes until they are evenly distributed throughout the dough. The dough will still be a bit sticky.

4. 4. First Fermentation (Bulk Ferment): Place the dough back into the clean bowl, cover it with a damp kitchen towel or plastic wrap, and let it rest at room temperature (ideally 70-75 F) for 4-6 hours. During this time, perform a series of “stretch and folds” every 30-60 minutes for the first 2 hours. To do this, gently grab a portion of the dough, stretch it upwards, and fold it over itself. Rotate the bowl and repeat 3-4 times. The dough should become smoother and more elastic, and you’ll notice it starting to rise.

5. 5. Shape and Cold Proof: After the bulk ferment, the dough should have increased in volume by about 30-50%. Gently turn the dough out onto a lightly floured surface and shape it into a round or oval loaf. Place the shaped dough into a floured banneton basket or a bowl lined with a floured kitchen towel, seam-side up. Cover with plastic wrap and refrigerate for 8-12 hours, or up to 24 hours. This cold proof develops flavor and makes the dough easier to handle.

6. 6. Preheat Oven and Bake: About an hour before baking, place a Dutch oven with its lid into your oven and preheat to 450 F (232 C). Once preheated, carefully remove the hot Dutch oven. Gently invert the cold dough from the banneton into the hot Dutch oven. Score the top of the dough with a sharp knife or razor blade (a simple “X” or a single slash works well).

7. 7. Bake Covered, Then Uncovered: Place the lid back on the Dutch oven and bake for 30 minutes. After 30 minutes, remove the lid and continue baking for another 15-20 minutes, or until the crust is deeply golden brown and the internal temperature reaches 200-210 F (93-99 C).

8. 8. Cool Completely: Carefully remove the bread from the Dutch oven and transfer it to a wire rack. This is a crucial step! Let the bread cool completely for at least 1-2 hours before slicing. Slicing too early can result in a gummy texture.
