Bake Sourdough Bread
After 90 min: A crusty, tangy sourdough loaf with open crumb structure
Sourdough is different from other bread baking because the yeast doing the work is alive — wild fermentation you cultivate over days, not a packet you dissolve in water. That living element gives sourdough its distinctive tang, its complex crumb, and its reputation for difficulty. This plan won't make it effortless, but it makes the process legible: you'll understand what's happening at each stage and why, which is what separates bakers who get consistent results from those who get lucky ones.
The session covers mixing and autolyse, bulk fermentation, pre-shaping and proofing, scoring, and baking in a Dutch oven. The bulk fermentation and overnight cold proof can't be rushed — time is doing real work that speed can't replicate. The plan's structure accounts for this by teaching you what to look for at each stage to judge readiness, rather than following rigid timers. The oven spring that happens when a scored loaf hits a hot Dutch oven is one of the most satisfying moments in all of baking.
Temperature is what most intermediate sourdough bakers are still learning to read. Your starter's activity, your kitchen's ambient temperature, and the dough temperature all affect fermentation speed — meaning the same recipe behaves differently in July and January. This session builds the baseline. Subsequent bakes develop the judgment that comes from watching dough across different conditions and seasons.
What you need
The 90-Minute Plan
Combine flour and water (80% hydration), mix until shaggy. Let rest 30 minutes. Add your active, bubbly starter and salt. Mix thoroughly.
Perform 4 sets of stretch-and-fold over 30 minutes at room temperature. Turn out onto the bench, shape gently. Bulk ferment 4-5 hours until 50-75% rise.
Pre-shape into a round, rest 20 minutes. Final shape with tension, seam side up in floured banneton. Cold proof in fridge overnight (12+ hours).
Preheat Dutch oven to 500°F. Turn dough onto parchment, score with a knife (¼ inch deep, 30-degree angle). Bake covered 20 minutes, uncovered 25-30 minutes until deep brown.
Cool on wire rack for at least 1 hour before slicing. The crust should crackle and crunch. The interior should have good oven spring and open crumb.
The overnight cold proof is essential—it develops flavor and makes the dough easier to score. Oven spring happens when you score properly, so be confident with your cuts.
