Method
Mix the flour and water

In a large bowl, combine 360 g of bread flour, 90 g of whole wheat flour, 30 g of dark rye flour, and 360 ml of water at about 24°C (75°F). Mix by hand until no dry pockets remain; the dough will look rough and feel sticky. Cover the bowl and let the flour hydrate for 30 minutes.
30:00Add the starter and salt

Add 100 g of active sourdough starter and sprinkle 10 g of fine sea salt across the dough. Pinch, fold, and squeeze the dough, rotating the bowl as you work. Begin checking after 5 minutes and continue for up to 7 minutes, until the starter is evenly distributed and the dough feels cohesive. Cover and rest for 15 minutes.
00:05:0000:07:0000:15:00Build strength with folds

With a damp hand, lift one side of the dough until it stretches, fold it over the center, and repeat from the remaining three sides. Cover and rest for 30 minutes. Complete two more sets of folds at 30-minute intervals. By the final set, the dough should feel smoother, hold its shape more readily, and show a few bubbles near the surface.
30:00Let the dough ferment
Cover the bowl and leave the dough at 21°C to 24°C (70°F to 75°F) for 4 to 6 hours. Begin checking at 4 hours. The dough is ready when it has risen by roughly half to three-quarters, looks aerated around the edges, and jiggles softly when the bowl is moved; do not wait for a full doubling.
4:00:00Shape and proof the loaf

Dust a proofing basket or a towel-lined bowl with 8 g of rice flour. Turn the dough onto a clean counter and draw the edges toward the center to form a loose round. Rest uncovered for 20 minutes. Flip the round, pull it gently against the counter to tighten the surface, and place it seam-side up in the prepared basket. Cover and proof at room temperature for 1 1/2 to 2 hours. Start checking after 1 1/2 hours; a fingertip pressed lightly into the dough should leave an indentation that returns slowly but does not fill at once.
00:20:0001:30:00Preheat and score the loaf

During the final 45 minutes of proofing, place a heavy lidded Dutch oven on a rack in the lower third of the oven and preheat to 250°C (480°F). Turn the loaf onto parchment paper. Use a bread lame or very sharp knife to make one confident slash about 1 cm (3/8 in) deep across the top, keeping fingers clear of the blade.
45:00Bake until deeply browned
Carefully lower the scored loaf into the hot Dutch oven using the parchment as a sling and cover with the lid. Reduce the oven to 240°C (465°F) and bake for 20 minutes. Remove the lid, reduce the oven to 230°C (450°F), and bake for 20 to 25 minutes more, checking first at 20 minutes. The loaf should be deep chestnut brown and register at least 96°C (205°F) in the center when checked with an instant-read thermometer.
00:20:0000:20:00Cool before slicing
Lift the loaf from the Dutch oven and place it on a wire rack. Let it cool for at least 2 hours before cutting so steam can escape gradually and the crumb can finish setting.

Smart Substitutions
- No dark rye flour? Replace it with an equal weight of whole wheat flour. The loaf will be slightly less earthy but will keep its rustic character.
- Prefer a milder whole-grain flavor? Replace half of the whole wheat flour with the same weight of bread flour for a lighter crumb and gentler wheat flavor.
- No rice flour? Dust the basket lightly with whole wheat flour. Use only enough to prevent sticking because it absorbs moisture more readily.
- No Dutch oven? Bake on a thoroughly preheated baking stone or steel beneath an inverted deep metal roasting pan for the first 20 minutes, then remove the cover to finish browning.
Tips and Variations
- Weigh the flours whenever possible; cup measurements can pack differently and change the dough texture.
- Dampen your hands before each fold so the dough stretches without clinging to your fingers.
- Let the crust reach a deep brown rather than stopping at pale gold; the darker finish brings out the grain flavor.
What Went Wrong?
- Dough remains very slack Add one extra set of folds and give the dough more fermentation time until it feels elastic and aerated. Avoid working in a large amount of extra flour.
- Loaf spreads after turning out Score and bake it promptly. Next time, tighten the final shape more firmly or shorten the final proof if the dough felt fragile and overexpanded.
- Crumb is dense Use a starter that rises strongly after feeding and allow bulk fermentation to continue until the dough shows clear bubbles and a substantial rise.
- Center feels gummy Confirm the loaf reaches at least 96°C (205°F), then allow the full 2-hour cooling period before slicing.
- Crust stays pale Continue baking uncovered for a few more minutes and make sure the Dutch oven was fully preheated before the loaf went in.
