Dough
Mix the flours and 350g of the water until no dry flour remains. Cover and rest 45 minutes.
Work in the starter by squeezing through your fingers. Add the salt dissolved in the remaining 25g water. Rest 30 minutes.
Over 4 to 5 hours, perform 4 sets of stretch and folds every 30 minutes, then leave undisturbed until dough has grown 50 to 60 percent.
Pre-shape into a round, rest 20 minutes, then do your final shaping — build tension across the surface by dragging the dough toward you.
Place seam-side up in a floured banneton. Cover and refrigerate overnight (8 to 16 hours).
Preheat oven to 250C (480F) with a Dutch oven inside for 45 minutes. Score the cold dough, lower into the Dutch oven. Bake covered 20 minutes, then uncovered 20 to 25 minutes until deeply dark. Cool at least 1 hour before cutting.
Origin story
Sourdough is the oldest form of leavened bread, with evidence going back 14,000 years. The country loaf has its spiritual home in French artisan baking, popularized globally by American bakers like Chad Robertson of Tartine Bakery.
