Ingredients

• Bread flour or all-purpose flour: 500g (bread flour’s higher protein content gives better structure)
• Water: 350g, filtered if your tap water is heavily chlorinated
• Salt: 10g fine sea salt or kosher salt
• Active sourdough starter: 100g, fed and bubbly

Starter

Creating and maintaining your sourdough starter is the foundation of great bread. You’re cultivating wild yeast and lactobacillus bacteria that’ll leaven your loaf and create that signature tang we all crave.

If you’re building from scratch, it’s straightforward but requires patience. Mix equal parts flour and water in a jar and let it sit at room temperature. Feed it daily by discarding half and adding fresh flour and water. Within 5-10 days, you’ll see consistent bubbling and rising. Whole wheat or rye flour in those first few days jumpstarts activity because they’ve got more nutrients for the microbes.

Here’s your basic feeding routine:

1. For countertop storage (if baking multiple times weekly): Feed once or twice daily using a 1:1:1 ratio—equal weights of starter, flour, and water. If keeping 50g starter, add 50g flour and 50g water.
2. For refrigerator storage (occasional baking): Feed once weekly. Pull it out, feed it, let it bubble on the counter for a few hours, then refrigerate.
3. Before baking: Remove the starter from the fridge the night before, feed it, and let it reach room temperature and peak activity before mixing your dough.

A healthy starter doubles or triples within 4-8 hours of feeding, depending on temperature. It should smell pleasantly tangy—like yogurt or beer—with tons of bubbles throughout. The top domes up at peak activity. If you see a layer of liquid (hooch) on top or it smells like nail polish remover, just feed it a couple of times, and it’ll bounce back.

Your starter’s ready to use when it’s at its peak: doubled in size, bubbly throughout, and showing that characteristic dome on top.

Mixing & Kneading

White sourdough doesn’t need aggressive kneading—we’re building strength gently through time and technique. The process relies on autolyse and stretch-and-fold methods that develop gluten without overworking the dough.

Follow these steps for mixing and developing your dough:

1. Start with autolyse: Mix just your flour and water in a large bowl until no dry bits remain. Cover and rest for 30-60 minutes. During this time, flour absorbs water and enzymes begin breaking down proteins, giving your dough a head start on gluten development.
2. Add starter and salt: After autolyse, add your active starter on top of the dough and dimple it in with your fingers. Sprinkle salt over everything and work it in using a pinching and folding motion until incorporated.
3. First stretch and fold: Wet your hands to prevent sticking. Reach under one side of the dough, stretch it upward without tearing, and fold it over itself. Rotate the bowl 90 degrees and repeat on all four sides. Cover the bowl.
4. Continue folding: Perform additional stretch and folds every 30 minutes for the next 2-3 hours (typically 4-6 sets total). Each time, wet your hands first, then stretch and fold all four sides.
5. Watch the transformation: With each set, you’ll feel the dough becoming stronger, smoother, and more elastic. Early on, it’ll be shaggy and rough. By the final set, it should hold its shape beautifully instead of spreading like batter.

The key is reading your dough’s texture. If it tears easily, give it more resting time between folds. If it feels slack and spreads too much, add another set to tighten things up. This gentle approach builds exactly the structure you need without incorporating too much air that would close up your crumb.

Fermentation

Bulk fermentation is where your dough transforms from a sticky mass into an airy, flavorful masterpiece. Wild yeast and bacteria produce carbon dioxide to inflate the dough while creating those complex sourdough flavors you can’t get any other way.

Here’s how to nail your fermentation:

1. After your final stretch and fold, cover the bowl and let it rest at room temperature. The ideal fermentation temperature is 75-78°F, but work with what you’ve got. Warmer speeds things up; cooler slows them down.
   
2. Find a warm spot in your kitchen if temperatures are low. Try on top of the fridge, near the stove, or inside your oven with just the light on. Even a mug of hot water sitting next to the dough in your microwave works.
3. Watch for volume increase of 50-75%—not necessarily doubled, but definitely puffed up and airier. This typically takes 4-8 hours, depending on temperature and starter strength. Summer might mean 5 hours; winter could push 8 or more.
4. Check the visual cues: The top should be slightly domed, not flat or collapsed. If using a clear container, you’ll see bubbles of various sizes throughout the sides.
5. Do the poke test: Gently press the surface with a fingertip. The dough should feel soft and pillowy. The indent should slowly spring back but leave a slight impression. If it springs back immediately, give it more time. If it stays collapsed, you’ve gone too far.

Stop watching the clock obsessively—your dough will tell you when it’s ready. Temperature, starter strength, and hydration all affect timing, so those recipe times are just guidelines. Trust what you’re seeing and feeling in the bowl more than any timer.

Shaping

Shaping happens in two stages, and both matter for getting a loaf that rises up instead of spreading out flat. After bulk fermentation ends, turn your dough onto a lightly floured surface. Using a bench scraper, gently gather it into a rough round. Let it rest uncovered for 20-30 minutes—this “bench rest” relaxes the gluten so your final shaping doesn’t fight you.

For a classic boule (round loaf), flour the top of your pre-shaped round and flip it over. Pull the edges up and into the center, working around in a circle, creating overlapping folds. Once you’ve gone all the way around, flip it back over so the seam’s on the bottom. Cup your hands around the dough and drag it toward you across the counter, creating tension on the surface. Rotate and drag again until that outer skin is taut.

If you prefer a batard (oval shape), gently stretch your pre-shaped round into a rectangle. Fold the sides toward the middle, then roll it up from the bottom, creating tension as you roll. Seal the seam by pinching it together, then drag it on the counter to tighten.

That taut outer skin isn’t just aesthetics—it gives your bread structure to rise upward, helps it release cleanly from your proofing basket, and creates a smooth surface for scoring. Be firm without degassing all those bubbles you worked so hard to develop. Transfer your shaped dough seam-side up into a floured banneton or bowl, cover it, and refrigerate for your final proof.

Baking

Baking transforms your carefully fermented dough into crusty, golden perfection. The secret? Intense heat and steam work together to create a dramatic oven spring and that signature crackly crust.

Follow these steps for bakery-quality results:

1. Preheat your Dutch oven for a full hour at 500°F. Don’t skip this—cast iron takes time to heat through, and you need every inch radiating heat when your dough hits it.
2. Prepare your dough for baking: Remove it from the fridge (cold dough scores easier and gives better oven spring). Dust the top with flour and turn it out onto parchment paper.
3. Score decisively: Using a sharp blade or razor, make one clean slash at a 30-45 degree angle, about 1/2-inch deep. This cut directs where the dough expands. Be confident and do it in one smooth motion.
4. Load the dough: Carefully transfer it into the screaming-hot Dutch oven using the parchment as a sling. Immediately cover with the lid.
5. Bake covered for 20 minutes at 450°F (drop from the preheat temp). The lid traps steam from the dough, keeping the crust soft enough to expand fully.
6. Remove the lid and continue baking for 20-30 minutes until you’ve got a deep golden-brown crust. This phase develops color and crunch.
7. Check doneness using an instant-read thermometer—you’re shooting for 205-210°F in the center. The bottom should sound hollow when tapped.
8. Cool completely before slicing—at least an hour, preferably two. Cutting into hot bread compresses the crumb and releases all that trapped steam. Use that time to prep whatever you’re planning to slather on it, because fresh sourdough with good butter is the whole point of this operation.
