Do I need bread flour?
No, but it helps. Bread flour has more protein, which usually means a taller loaf and chewier crumb. If using all-purpose flour, start with about 310 to 325 g water since AP flour often absorbs a little less.
How do I know my starter is ready?
Use your starter when it is active, bubbly, and at or near peak. A simple test: after feeding, it should roughly double in 4 to 8 hours (timing depends on temperature). It should smell pleasantly tangy, not harshly boozy or like nail polish remover.
What “100 g active starter” means: Feed your starter and use it when it is domed on top, full of bubbles, and still rising or just starting to level off. If you want a simple feeding example, try 1:1:1 (starter:water:flour by weight) and use it at peak.
Does starter hydration matter?
Yes, a little. This recipe assumes a 100% hydration starter (equal weights flour and water). If yours is stiffer or more liquid, your dough hydration will change. Keep going and use the dough cues, or adjust by adding a little extra water or flour during mixing to match the feel described.
My dough feels sticky. Did I ruin it?
Probably not. Higher hydration dough is sticky early on. With each stretch and fold, it gets smoother and stronger. Keep your hands damp, and resist adding lots of flour, which can make the loaf dense.
Can I bake without a Dutch oven?
Yes. Use a heavy lidded oven-safe pot if you have one. If not, bake on a preheated stone or sheet pan and create steam by placing a metal pan on the bottom rack and pouring in hot water right after the bread goes in. The crust may be a little less dramatic, but it still works.
Why did my loaf turn out flat?
Common culprits: overproofing (dough fermented too long), weak shaping (not enough surface tension), or starter not strong enough. The overnight fridge proof helps a ton with structure and scoring.
Why is my crumb gummy?
Most often: it needed more bake time or it was sliced while warm. Let it cool at least 1 hour, ideally 2. Also make sure the center hits around 205 to 212°F if you are using a thermometer.
Can I bake straight from the fridge?
Yes. Cold dough is easier to score and tends to hold its shape better. If your loaf looks very tight and not puffy after the cold proof, let it sit at room temp for 30 to 60 minutes before baking, then score and bake as directed.
