Ingredients
Method
- Mix flours and water, rest 30 minutes. Add starter and salt, mixing until incorporated.
- Bulk ferment 2 hours at room temperature, performing 3 to 4 sets of stretch and folds every 30 minutes.
- On a floured surface, pat dough into a 12x16-inch rectangle. Spread with butter, sprinkle with cinnamon sugar and raisins, leaving a 1-inch bare border on one long edge.
- Roll up tightly from the opposite long edge, pinch the seam closed, and place seam-side down in a greased 9x5-inch loaf pan.
- Cover and proof until the dough rises about 1 inch above the pan rim, 2 to 4 hours at room temperature or overnight in the fridge.
- Preheat oven to 450°F (230°C) with a Dutch oven inside. Score the loaf, transfer to the hot vessel, cover and bake 30 minutes, then uncover and bake 20 to 25 minutes until deeply golden. Cool on a rack before slicing.
Notes
Hands-on time runs about 30 minutes total; bulk fermentation and proofing take 6 to 8 hours room temperature or 8 to 12 hours cold-proofed. Soak dry raisins in hot water for 10 minutes and drain well to prevent them from burning at the edges during baking.
