Combine all of the ingredients in a large bowl and mix until a sticky dough forms.
Cover the bowl and let rest for about 5-6 hours at room temperature (ideally between 70 to 75 degrees).
With wet hands, fold the dough over on itself 3 or 4 times. Recover the bowl and allow dough to ferment for at least 2 more hours.
Generously dust a banneton with flour.
Scrape dough out onto a lightly floured work surface.
Shape dough into a ball with a smooth, unbroken surface, using just enough flour on the surface to keep it from sticking.
Transfer, smooth-side down, to banneton.
Pinch together the rougher edges of the surface toward the center to smooth them and maintain the round ball shape.
Cover and refrigerate the dough for 12 hours to slow the fermentation process.
Remove from the refrigerator and let the dough rise in a warm spot until it springs slowly back and retains a slight indentation when poked gently with a finger (about 4 to 5 hours).
Preheat oven to 450 degrees, and line a rimmed baking sheet with parchment paper or silicone baking mat.
Dust surface of dough with flour.
Gently invert banneton and transfer dough onto prepared baking sheet.
Gently brush excess flour off of dough.
Score the top of the dough about 1/8″ deep with a sharp knife to create a shallow slit running across the center.
Lightly mist entire surface of the dough with water.
Bake in the center of preheated oven for about 25-30 minutes, or until browned.
Transfer the bread to a rack to cool completely (do not slice loaf while it is still warm).

Preheat oven to 425 degrees and prepare muffin tins (grease or line) or silicone muffin cups. This recipe will make about 15 muffins.
Mix the crumb topping ingredients in a small bowl, blending by hand or with a fork until crumbly.
In a large bowl, sift together the flour, baking soda, baking powder, salt and spices.
In a medium-sized bowl, whisk together the eggs, oil, brown sugar and sourdough starter.
Add the sourdough mixture to the dry ingredients and gently fold in until the flour is mostly dissolved, making sure not to over mix.
Fold in the carrots until evenly mixed throughout; the batter will be thick.
Scoop the batter into the prepared muffin cups, filling about 3/4 full.
Sprinkle about 1-1/2 tablespoons of the crumb topping over the top of each muffin.
Bake at 425 degrees for 5 minutes. Turn the heat down to 350 degrees (don’t open the door) and cook for 15-20 minutes longer, until the muffins are lightly browned and cooked through.
