In a small bowl, add the cranberries, juice of one orange, and the orange zest. Mix well and set it aside, letting the cranberries rehydrate for a few minutes.
In a large bowl, mix the sourdough starter with water. Stir until the starter is dissolved. Add the flour, salt, honey, cranberries, orange juice, and orange zest.
Mix until a shaggy dough forms. Cover with a damp towel and let it rest for 1 hour.
After 1 hour, perform your first set of stretch and folds. Take one side of the dough and lift it into the center of the dough. Continue doing that until the bowl is entirely turned and the dough is smooth.
Cover the dough and let it rise at room temperature for 6-8 hours, performing 3-4 sets of stretch and folds every 30 minutes during the first two hours.
Once the bulk fermentation is complete, shape the dough into a round boule.
Cold Ferment time! If you are not baking the loaf now, place the dough seam-side up into a floured banneton (proofing basket) or a large bowl. Cover the dough and place it in the refrigerator for up to 24 hours.
When you are ready to bake, Preheat your oven to 450°F with a Dutch oven inside. Once heated, carefully transfer your loaf into the hot Dutch oven, score the top, and cover with the lid. Bake for 30 minutes with the lid on, then remove the lid and bake for an additional 30 minutes until golden brown.
