Instructions

1. 1

   Test your starter

   Before you begin, your starter must be active and hungry. Drop a spoonful into a glass of room temperature water. If it floats, you're ready to proceed. If it sinks, feed it equal parts flour and water by weight, wait 4-6 hours until it doubles, then test again. A sluggish starter produces dense, sour bread. A vigorous one gives you lift and complexity.

   The float test is reliable but not infallible. A starter that has doubled in size and shows a domed top with bubbles throughout is ready, even if it barely floats.
2. 2

   Mix the dough

   In a large bowl, combine the warm water and starter, stirring until the starter dissolves into cloudy suspension. Add the flour and mix with your hand or a wooden spoon until no dry flour remains. The dough will look shaggy and feel sticky. This is correct. Cover with a damp kitchen towel and let rest for 30-45 minutes. This autolyse allows the flour to fully hydrate and begins gluten development before you add salt.

   Water temperature matters. Too cold slows fermentation. Too hot kills yeast. Aim for 78-82°F, which feels barely warm to the touch.
3. 3

   Add salt and develop gluten

   Sprinkle the salt over the dough and add 2 tablespoons of water to help it dissolve. Using wet hands, squeeze the dough repeatedly, folding it over itself, until the salt is fully incorporated. The dough will feel tighter and more cohesive. Now perform the first set of stretch and folds: wet your hand, slide it under one side of the dough, stretch it upward without tearing, and fold it over the center. Rotate the bowl 90 degrees and repeat. Do this four times to complete one set.

4. 4

   Bulk fermentation with folds

   Over the next 3-4 hours, perform 4-6 sets of stretch and folds, spaced 30-45 minutes apart. With each set, you'll notice the dough becoming smoother, stronger, and more elastic. It will hold its shape better and feel less slack. By the final set, the dough should stretch into a thin, translucent windowpane when pulled gently between your fingers. Between folds, keep the bowl covered in a warm spot, ideally 75-78°F.

   If your kitchen runs cold, place the covered bowl in your oven with just the light on, or set it atop your refrigerator where heat rises.
5. 5

   Judge fermentation

   Bulk fermentation is complete when the dough has increased in volume by 50-75%, shows bubbles on the surface and along the sides of the bowl, and has a slightly domed top. Poke it gently with a wet finger. The indentation should spring back slowly but not completely. This indicates the yeast has produced enough gas while leaving room for the final rise. If the dough feels slack and deflates when touched, it has overproofed. You can still bake it, but expect a flatter loaf with a more sour flavor.

6. 6

   Pre-shape the dough

   Lightly flour your work surface and turn the dough out. Using a bench scraper, gently shape it into a rough round by tucking the edges underneath, creating surface tension on top. Don't worry about perfection here. Let the dough rest uncovered for 20-30 minutes. This bench rest relaxes the gluten and makes final shaping easier. The dough will spread slightly but shouldn't flatten completely.

7. 7

   Final shaping

   Dust your hands and the top of the dough lightly with flour. Flip it over so the floured side is down. Working quickly, stretch the four sides of the dough outward, then fold each toward the center like an envelope. Flip the dough seam-side down. Using your bench scraper and the heel of your hand, drag the dough toward you in short strokes, allowing the friction of the work surface to create tension on the outer skin. Rotate and repeat until you have a taut, smooth boule with a defined seam on the bottom.

8. 8

   Cold proof overnight

   Generously dust a proofing basket or a bowl lined with a floured kitchen towel with rice flour or a 50/50 blend of rice and bread flour. Place the shaped dough seam-side up in the basket. Cover tightly with plastic wrap or slip into a plastic bag. Refrigerate for 8-16 hours. This cold retard develops flavor and makes the dough easier to score. The long, slow fermentation produces the complex, tangy notes that distinguish real sourdough.

   Rice flour prevents sticking far better than wheat flour. It doesn't absorb moisture the same way. If you only have bread flour, use it liberally and accept that some sticking may occur.
9. 9

   Preheat with the Dutch oven

   One hour before baking, place your Dutch oven with its lid inside your oven and heat to 500°F. The pot must be screaming hot. This replicates the steam-injected environment of a professional deck oven, trapping moisture released from the dough to produce that crackling, blistered crust. Cast iron holds heat beautifully. Enameled cast iron works equally well.

10. 10

    Score and load

    Remove the dough from the refrigerator. It should feel firm but not rigid, and it should have visibly grown, though less dramatically than at room temperature. Turn it out onto a piece of parchment paper. Using a razor blade or very sharp knife held at a 30-degree angle, score the top with a single decisive slash about 1/2 inch deep, or create a square pattern, or whatever design suits you. Work quickly. Cold dough scores cleanly. Warm dough drags.

    The score isn't decoration. It controls where the loaf expands during the violent oven spring of the first ten minutes. Without it, the crust would tear unpredictably.
11. 11

    Bake covered

    Carefully remove the blazing hot Dutch oven from your oven. Remove the lid. Using the parchment as a sling, lower the dough into the pot. Replace the lid immediately. Return to the oven and reduce the temperature to 450°F. Bake covered for 20 minutes. The trapped steam allows the crust to stay flexible while the dough expands dramatically. You'll hear it crackling and popping. This is the sound of good bread.

12. 12

    Bake uncovered to finish

    Remove the lid and continue baking for 20-25 minutes until the crust is deeply burnished, the color of mahogany or dark amber. Don't fear the color. Pale bread is undercooked bread, gummy in the center and lacking in flavor. The internal temperature should reach 205-210°F. When you tap the bottom of the loaf, it should sound hollow, like a drum.

13. 13

    Cool completely

    Transfer the loaf to a wire rack and resist the urge to cut into it for at least one hour, preferably two. This is the hardest part. The bread is still cooking inside, the starches setting, the moisture redistributing. Cut too soon and you'll find a gummy interior and a crust that goes soft within minutes. Patience rewards you with a crumb that's custardy and open, a crust that stays crisp for hours.

Chef Tips

• •Maintaining a sourdough starter is simpler than the internet suggests. Feed it once daily if kept at room temperature, or once weekly if refrigerated. Equal parts flour and water by weight. Discard before feeding to keep quantities manageable. A healthy starter smells pleasantly yeasty, like overripe fruit or mild beer. A neglected one smells of acetone. Feed it twice and it will recover.
• •The hydration of this dough is 75%, which is moderate and forgiving for beginners. As you gain confidence, increase the water to 80% or higher for a more open crumb, accepting that the dough will be stickier and harder to shape.
• •Your hands are your best tools for mixing and shaping. Keep them wet to prevent sticking. Resist the urge to add flour to the dough itself. Wetter dough produces better bread.
• •Bread baked in a Dutch oven will be darker on the bottom. If this bothers you, slide a baking sheet beneath the pot for the uncovered portion of baking.
• •Store cooled bread cut-side down on a wooden board. Never refrigerate it. The cold accelerates staling. A proper loaf keeps well for 3-4 days at room temperature. After that, slice and freeze for toast.

Advance Preparation

• •The dough can cold-proof in the refrigerator for up to 48 hours, though flavor becomes more assertively sour after the first day.
• •If your schedule requires flexibility, the dough can be shaped and placed directly in the freezer. Bake from frozen, adding 10-15 minutes to the covered baking time.
• •Active starter can be built from a refrigerated starter with two feedings over 24 hours. Plan accordingly.
