1. 1. Ensure Your Starter is Robust and Active: Your sourdough starter should be fed and allowed to mature until it’s very active, bubbly, and has roughly doubled or tripled in size. Perform the “float test”: drop a small spoonful of starter into a glass of water. If it floats, it’s ready to use. If it sinks, it needs more time to develop.

2. 2. Proper Hydration is Key: When mixing your dough, aim for a shaggy, slightly sticky consistency. If your dough feels stiff and dry, gradually add a little more water (a tablespoon at a time) until it reaches the right consistency.

3. 3. Develop Gluten Effectively with Stretching and Folding: After mixing, perform a series of “stretch and folds” during the bulk fermentation. Every 30-60 minutes for the first 2-3 hours, gently stretch a portion of the dough up and fold it over itself, rotating the bowl. Do this 4-6 times per session.

4. 4. Monitor Bulk Fermentation, Don’t Just Rely on Time: The dough should increase in volume by about 30-50% and feel noticeably lighter and airy. Look for bubbles on the surface and along the sides of the bowl. Perform the “poke test”: gently poke the dough with a wet finger; if the indentation slowly springs back, it’s likely ready.

5. 5. Gentle Shaping for a Strong Surface Tension: When shaping your dough, be firm but gentle. Create a taut “skin” on the outside of the loaf. Avoid degassing the dough too much during shaping. The dough should feel like a firm, round cushion after shaping.

6. 6. Cold Proofing for Flavor and Structure: After shaping, place your dough in a floured banneton or bowl, cover it, and refrigerate it for 12-24 hours.

7. 7. Bake with High Heat and Steam: Preheat your oven with a Dutch oven inside to 450-500 F (230-260 C). Bake with the lid on the Dutch oven for the first part of the bake.
