Making Chocolate Cherry Sourdough Bread can be straightforward if you follow these steps carefully:

1. Mix the Dough: In a large mixing bowl, combine both flours and water. Stir until no dry flour remains.

2. Add Sourdough Starter: Allow the mixture to rest for about 30 minutes. Next, add the active sourdough starter and mix thoroughly.

3. Incorporate Salt: Add the salt and sugar (if using) to the dough. Mix well until fully combined.

4. Bulk Fermentation: Cover the bowl with a damp cloth or plastic wrap. Let it ferment at room temperature for about 4-12 hours until the dough has doubled in size.

5. Prepare Mix-ins: While the dough ferments, chop the dark chocolate and cherries. Set aside.

6. Stretch and Fold: Once the dough is ready, turn it out onto a lightly floured surface. Stretch the dough and fold it over itself several times to incorporate air.

7. Add Chocolates and Cherries: Gently knead the chopped chocolate and cherries into the dough until evenly distributed.

8. Pre-shape the Dough: Form the dough into a loose ball. Allow it to rest for about 30 minutes.

9. Shape the Dough: After resting, shape the dough into a round or oval loaf, depending on your baking vessel.

10. Proofing: Place the formed dough into a floured proofing basket or bowl. Cover and let it proof for another 1-2 hours.

11. Preheat the Oven: About 30 minutes before baking, preheat your oven to 450°F (230°C). If using a Dutch oven, place it in the oven to heat up.

12. Score the Dough: Once the dough has proofed, carefully turn it out onto a piece of parchment paper. Use a sharp knife or razor to score the top; this allows for better expansion during baking.

13. Bake the Bread: If using a Dutch oven, carefully remove it from the oven, lift the parchment paper with the dough, and place it inside. Cover and bake for 30 minutes. Then, remove the lid and bake for an additional 15-20 minutes until the crust is deep golden brown.

14. Cooling: Once baked, transfer the bread to a cooling rack. Allow it to cool completely for at least 1 hour before slicing.

By following these steps, you will create an incredible loaf of Chocolate Cherry Sourdough Bread that will wow both friends and family.
