What is sourdough bread, exactly?
Sourdough is bread leavened with a starter, a culture of wild yeast and friendly bacteria. It rises more slowly than commercial yeast bread, which is where the flavor comes from.
How do I know my starter is ready to bake with?
A ready starter looks bubbly and lively and smells pleasantly tangy. The most reliable sign is behavior: after feeding, it should rise noticeably (often doubling) within 4 to 8 hours at warm room temperature. If it is sluggish, give it a couple daily feedings before baking.
What kind of starter is this recipe written for?
This recipe assumes a 100% hydration starter (fed with equal weights flour and water). If your starter is much thicker or thinner, your dough will feel different. Trust the dough and hold back a splash of water if it seems overly slack.
My dough is sticky. Did I mess it up?
Sticky is normal. Use wet hands for stretch-and-folds and a bench scraper for shaping. If the dough is soupy and will not hold any shape, your flour may be lower protein or your kitchen may be warm. Next time, reduce water by 20 to 30 grams and see how it behaves.
How do I get a more sour flavor?
For more tang, do a longer, cooler proof. The easiest move: refrigerate the shaped dough overnight (8 to 16 hours) before baking.
Do I need a Dutch oven?
It is the simplest way to trap steam for great crust. If you do not have one, bake on a preheated sheet pan or stone and add steam by placing a small metal pan on the bottom rack and carefully pouring in hot water when the bread goes in.
Why is my loaf gummy inside?
Usually one of three things: it was underproofed, underbaked, or sliced while still hot. Let it cool at least 1 hour, and make sure the crust is deep golden brown before pulling it. If you want a sure thing, check doneness with a thermometer. Aim for about 208 to 212°F in the center.
