Bake Real Bread From a Live Starter: A Calm Beginner's Guide to Sourdough

Sourdough has a reputation for being fussy. Between keeping a starter alive, watching the clock, and wrestling with sticky dough, a lot of people give up before their first decent loaf. The good news is that none of it is magic. It is just flour, water, salt, time, and a little attention to a few signals. This guide walks through the whole process in plain steps, with the common beginner mistakes called out so you can avoid them.

Start With a Healthy Starter

The starter is not a pet you have to spoil. It is a small jar of flour and water where wild yeast and bacteria live. Keep it fed and it stays alive. Ignore it and it slows down and gets thin on top.

• A healthy starter is bubbly and rises after feeding, then falls back down once it has eaten its food.
• Keep it simple. A 1:1:1 feeding ratio is a good rhythm for beginners: equal weights of starter, flour, and water. For example, 50 grams of starter, 50 grams of flour, and 50 grams of water.
• Read the ratio as starter, then flour, then water. So 1:1:1 means one part starter, one part flour, one part water, by weight.
• At a normal room temperature, a 1:1:1 feed peaks in about 4 to 6 hours. That means it is at its most active and ready to use.
• If you only bake once a week, keep the starter in the fridge between bakes. It ferments slowly when cold. Take it out and give it a feed the day before you want to bake.

Avoid tap water that is heavily chlorinated if you can. Most of the time it is fine, but if your starter seems sluggish, let the water sit out overnight or use filtered water.

Use Flour That Can Do the Job

Not all flour is equal when it comes to bread.

• Use bread flour if you can. It has more protein, roughly 12 to 14 percent, which gives the dough strength to hold its shape and rise well.
• All-purpose flour works, but the dough will be a little softer and need more care.
• Whole wheat flour adds flavor but rises less and can make a denser loaf. A mix of bread flour and a little whole wheat is a good place to start.

Mix the Dough and Let It Build Some Strength

The dough will be sticky at first. That is normal, not a sign you did something wrong.

• Combine the starter, water, flour, and salt until no dry bits are left, then let it rest for half an hour.
• Instead of kneading for a long time, use a few gentle folds. Every 30 minutes or so, grab one edge of the dough, lift it up and over the middle, and turn the bowl. Three or four folds across a couple of hours builds strength without the mess.
• Keep your hands wet or lightly floured when you handle sticky dough. It makes the dough much easier to work with.

Bulk Fermentation: Go by Feel and Temperature, Not a Hard Time

The biggest beginner mistake is waiting for the dough to double in size. Sourdough rises less than commercial-yeast bread, and the exact time depends on your kitchen.

• Warmer dough ferments faster. Cooler dough ferments slower. Expect a few hours at a comfortable room temperature, more if it is cool, less if it is warm.
• Look for a dough that is airy, puffy, and has grown noticeably, though not necessarily doubled.
• A good rule for beginners is to keep hydration moderate, around 70 to 72 percent. That means for every 100 grams of flour, use about 70 to 72 grams of water. Higher hydration doughs make a more open crumb but are harder to handle.
• If the dough spreads flat and collapses, you probably over-fermented it. Next time, stop a little earlier.

Shape, Proof, and Bake in a Hot Covered Pot

Once the dough has bulk-fermented, shape it gently and let it rest again for the final proof. Over-proofing makes a flat loaf, so do not let it go too long.

• Get the oven hot, around 450 to 475 degrees F, with a covered cast iron pot or Dutch oven inside.
• Carefully transfer the dough into the hot pot, cover it, and bake covered for the first stretch. The trapped steam keeps the crust from setting too early, which lets the loaf spring up.
• Uncover for the last stretch so the crust turns a deep golden brown.
• Let the loaf cool completely before slicing. Cutting into a hot loaf makes a gummy crumb.

When It Goes Wrong, Change One Thing

Sourdough is forgiving once you know which knob to turn. If a loaf comes out dense, flat, or gummy, do not overhaul everything. Change one variable at a time.

• Flat and spread out: the dough was over-fermented, or the starter was past its peak when you mixed it. Use the starter sooner and stop the bulk ferment earlier.
• Dense with a tight crumb: the dough was under-fermented, or the starter was not active enough. Give the dough more time and make sure the starter is bubbly before you use it.
• Gummy inside: the loaf was cut too soon, or it needed more time in the oven. Let the bread cool fully, and bake until the crust is deep brown.

Keep notes on what you changed. After a few loaves you will have a process that works in your kitchen, at your temperatures, with your flour. That is the whole point.
