Instructions

1. 1

   Mix flour and water

   Combine the flour and water in a large bowl. Mix with your hands until no dry patches remain. The dough will look shaggy and rough. This is right. Cover and let it rest for thirty minutes to one hour. This rest, the autolyse, allows the flour to hydrate fully. Gluten begins forming without any effort from you. Good bread rewards patience from the very first step.

   Water temperature matters. In summer, use cooler water. In winter, slightly warm. The dough should feel comfortable to the touch, like bathwater for a child.
2. 2

   Add starter and salt

   Scatter the salt over the dough. Dollop the active starter on top. Pinch and squeeze the dough, folding it over itself until the starter and salt are fully incorporated. This takes three to five minutes. The dough will feel tight and resistant at first, then relax as you work. When the surface looks smoother and you cannot see distinct pieces of starter, you are done.

   Your starter should be bubbly and doubled in size after feeding. If it floats in water, it is ready. If it sinks, feed it again and wait.
3. 3

   Build strength with folds

   Over the next four hours, stretch and fold the dough four times, once every thirty to forty-five minutes. Wet your hand, slide it under one side of the dough, stretch it up gently until you feel resistance, then fold it over the center. Rotate the bowl ninety degrees and repeat. Four stretches around the bowl equals one set. Cover between folds. Watch the dough transform. It begins slack and sticky. With each fold, it becomes smoother, stronger, and holds its shape better.

   Do not tear the dough. Stretch only until you feel it push back. You are building strength, not fighting it.
4. 4

   Bulk fermentation

   After the final fold, leave the dough covered at room temperature until it has grown by about fifty percent and feels airy when you gently poke it. This takes three to five hours depending on your kitchen and the vigor of your starter. Look for domed edges and small bubbles visible through the bowl. The surface should look alive, slightly domed, trembling when you move the container.

5. 5

   Shape the boule

   Flour your work surface lightly. Turn the dough out gently, disturbing the air inside as little as possible. Fold the edges toward the center, building tension on the surface. Flip it seam-side down. Cup your hands around the dough and drag it toward you, letting the friction of the counter tighten the surface. The skin should feel taut, like a drum. Do not overwork it. A few confident motions are better than many hesitant ones.

6. 6

   Final proof

   Line a bowl or banneton with a clean kitchen towel and dust it generously with rice flour or a fifty-fifty blend of rice and bread flour. Place your shaped dough seam-side up in the basket. Cover with plastic or a damp towel and refrigerate overnight, at least eight hours and up to fourteen. The cold slows fermentation and develops flavor. This is where sourdough becomes sourdough. Do not rush it.

   Rice flour prevents sticking better than wheat flour. It does not absorb moisture the same way.
7. 7

   Preheat with the pot

   One hour before baking, place your Dutch oven with its lid inside your regular oven. Heat to 500°F (260°C). The pot must be screaming hot. This creates the steam that gives sourdough its shattering crust. Without this trapped moisture, you will have good bread but not great bread.

8. 8

   Score and bake

   Remove the cold dough from the refrigerator. Turn it out onto a piece of parchment paper, seam-side down now. Using a razor blade or very sharp knife, slash the surface in one confident motion, holding the blade at a thirty-degree angle. The score should be a quarter-inch deep. This is where your loaf will bloom. Carefully lower the dough into the hot pot using the parchment as a sling. Cover immediately.

   Cold dough scores cleanly. Warm dough drags. Bake it straight from the refrigerator.
9. 9

   Bake covered then uncovered

   Bake covered at 500°F for twenty minutes. The steam trapped inside the pot allows the crust to stay flexible while the loaf expands. Remove the lid, reduce heat to 450°F (230°C), and bake another twenty to twenty-five minutes until the crust is deeply caramelized, almost mahogany. When you tap the bottom, it should sound hollow and resonant, like knocking on a wooden door.

10. 10

    Cool completely

    Transfer the loaf to a wire rack. Listen. You may hear it crackle as the crust contracts, what bakers call the song of bread. Let it cool for at least one hour before slicing. Cutting into hot bread releases steam and leaves the interior gummy. Patience, still. The bread finishes cooking as it cools.

Chef Tips

• •Find your flour source. A regional mill, a farmers market vendor, even a good natural foods store that stocks stone-ground options. The flour is eighty percent of your bread. Spend your attention there.
• •Your starter should smell pleasantly sour, like yogurt or ripe fruit. If it smells like nail polish remover, it has been neglected too long. Feed it twice a day for a few days until it recovers.
• •Humidity and temperature in your kitchen affect fermentation dramatically. In summer, expect faster rises. In winter, find a warm spot, perhaps near the oven or on top of the refrigerator.
• •The hydration here (seventy percent) is forgiving for beginners. As you gain confidence, try adding more water for a more open crumb. Work up to seventy-five or eighty percent.
• •Freeze one half of the loaf if you cannot finish it in three days. Slice first, then freeze. Toast directly from frozen.

Advance Preparation

• •The starter needs regular feeding to stay active. Plan to feed it twice in the day before you mix your dough, eight to twelve hours apart.
• •The cold proof can extend up to fourteen hours, making this bread perfect for a morning bake. Mix in the afternoon, shape in the evening, refrigerate overnight, bake when you wake.
• •Unbaked, shaped dough can be frozen in the banneton. Let it thaw overnight in the refrigerator, then bake as directed, adding five minutes to the covered bake time.
