Beginner sourdough bread
This round sourdough loaf has a deeply browned crust and an airy, gently chewy crumb. An active starter builds fermentation, gentle folds strengthen the dough, and a cold final proof makes scoring easier.

Method
- Stir 100 g active sourdough starter (wheat or rye) at 100% hydration into 350 g water, then mix in 500 g bread flour and 11 g fine salt until no dry flour remains. Knead by hand for 5 minutes until cohesive, aiming for a dough temperature of 24 to 25 °C (75 to 77 °F).Use recently fed starter that has at least doubled, is full of bubbles, and is at or just before its peak; the dough should remain slightly sticky, so do not add flour.
- Transfer the dough to a straight-sided container, mark its starting level, and cover. Let rise at 24 °C (75 °F) for 30 minutes.
- With damp hands, gently stretch one side of the dough upward and fold it over the center, repeating on all four sides. Cover and let rise at 24 °C (75 °F) for 30 minutes.Lift only as far as the dough stretches comfortably without tearing.
- Repeat the folds on all four sides. Cover and let rise at 24 °C (75 °F) for 30 minutes.
- Repeat the folds on all four sides, then cover and let rise at 24 °C (75 °F) for 2½ hours. Extend this phase as needed until the dough has grown about 50 to 75% from its starting volume, shows bubbles along the edges, and jiggles lightly when the container is moved.Total bulk fermentation usually takes 4 to 6 hours; use the marked starting level and the dough's appearance rather than the clock alone.
- Gently turn the dough onto the work surface and use a dough scraper to preshape it into a loose round. Cover and let rest at 24 °C (75 °F) for 20 minutes.Keep the handling gentle to preserve the gas built during bulk fermentation.
- Dust the proofing basket with 10 g rice flour, then turn the dough over, fold the edges inward, and roll or draw it into a firm round without tearing the surface. Place seam-side up in the basket, cover, and refrigerate at 4 °C (39 °F) for 12 hours, until slightly expanded and airy.Keep the dough refrigerated until baking.
- During the last 45 minutes of the refrigerator proof, preheat the conventional oven to 250 °C (475 °F) with the empty cast-iron Dutch oven and its lid inside. Turn the cold dough onto parchment rated for 250 °C (475 °F), score about 1 cm (½ in) deep, carefully lower it into the hot pot with the paper, cover, turn the oven down to 240 °C (475 °F), and bake for 20 minutes.Use oven mitts when handling both the pot and the lid.
- Carefully remove the hot lid, lift the loaf out with oven mitts, remove the parchment completely, and return the loaf to the pot without paper. Bake uncovered at 220 °C (425 °F) for 25 minutes, until deeply golden with a center temperature of 96 to 98 °C (205 to 208 °F), adding 5 to 10 minutes uncovered if needed.
- Remove the loaf from the pot and cool completely on a rack for 120 minutes before slicing.Store the fully cooled loaf at room temperature in a bread box or paper bag for up to 3 days; for longer storage, freeze in slices for up to 3 months.
Food safety
- Do not taste raw dough: raw flour can carry pathogens. Wash your hands and the counter after handling the dough.
- Contains: gluten (wheat, rye).

When it goes wrong
| What you see | Likely cause | Next time |
|---|---|---|
| The dough shows little growth during bulk fermentation. | The starter was not sufficiently active, or the dough was too cool. | Use starter at or just before its peak and check the dough and fermentation temperatures. |
| The dough tears during folding. | It is being stretched beyond its resistance. | Use damp hands and stop stretching before the dough begins to tear. |
| The dough feels unusually stiff and the crumb is tight. | Extra flour was worked into the dough during kneading. | Keep the specified flour quantity and accept some stickiness. |
| The loaf spreads and has a dense crumb. | Bulk fermentation ended before the dough developed enough gas. | Wait for the marked volume increase, edge bubbles, and light jiggle before preshaping. |
| The dough is slack, fragile, and difficult to shape. | Bulk fermentation continued beyond the dough's useful strength. | End bulk fermentation when the stated volume and texture cues appear rather than waiting for more growth. |
| The dough sticks to the proofing basket. | The basket was not evenly coated with rice flour. | Distribute the rice flour across the basket, including its sides. |
| The cooled crumb is gummy. | The loaf was underbaked or sliced before it cooled completely. | Check the center temperature and let the loaf cool fully on a rack before cutting. |
