How to Make Sourdough Bread from Starter: Foolproof Home Method & 24-Hour Timeline

Let's be real – my first attempt at making sourdough bread from starter was a disaster. The loaf came out dense as a brick, and my family politely called it "artisan doorstop". But after burning through 50+ kilos of flour (and tossing some truly sad loaves), I finally cracked the code.

Getting Your Starter Battle-Ready

If your starter isn't lively, forget about good bread. I learned this the hard way when my sleepy starter made flat pancakes instead of bread. Here's what actually works:

Pro Tip: Do the float test! Drop a spoonful of starter in water. If it floats like a cork, you're golden. If it sinks... give it another hour.

Feeding Ratios That Won't Fail You

Starter Condition Flour Type Water Temp Rise Time (70°F/21°C)
Freshly fed Bread flour 85°F/30°C 4-5 hours
From fridge Whole wheat 90°F/32°C 8-12 hours

I keep two starters now – one all-purpose for sandwich bread, one rye for tangy boules. Why? Because last Thanksgiving my all-purpose starter decided to take a vacation right when I needed it. Backup is key.

Essential Tools You Actually Need

Don't waste money like I did. You need just five things:

  • Digital scale ($15-25) – cups are useless for sourdough
  • Dutch oven (Lodge 5qt works great)
  • Razor blade for scoring (not knives!)
  • Banneton proofing basket (or colander lined with tea towel)
  • Dough scraper – plastic is fine

That fancy $200 bread lame? Used mine twice. Your utility razor works better.

The Magic Formula: Ingredients Breakdown

Ingredient Weight Baker's Percentage Why It Matters
Bread flour 500g 100% Higher protein = better oven spring
Water 350g 70% Warm (80°F/27°C) for starter activation
Active starter 100g 20% Not discard! Must pass float test
Salt 10g 2% Add after autolyse – kills yeast if added early

My 24-Hour Timeline (No Rush Baking)

Forget those "4-hour sourdough" recipes. Good bread takes time. Here's my weekend schedule:

9:00 AM Feed starter (1:5:5 ratio)
2:00 PM Mix dough (flour + water only)
2:30 PM Add starter + salt
3-7 PM Stretch & fold every 30 min (4x total)
8:00 PM Shape & into banneton
Overnight Fridge proof (12-15 hours)
Next day 10 AM Bake!
Watch Out: Kitchen colder than 70°F/21°C? Double bulk fermentation time. My winter fail #1: underproofed dough.

The Make-or-Break Steps Explained

Mixing without Murdering Your Starter

Combine flour and warm water first. Let it sit 30 min (autolyse). This isn't just chef talk – it makes dough silky. Then add starter and salt. Mix with wet hands until no dry spots.

Why wet hands? Dry flour on your skin will steal moisture from the dough. Learned that after making crusty knuckles bread.

The Fold Ritual

Every 30 minutes: Grab dough edge, stretch upward, fold over center. Rotate bowl 90°. Repeat 4 times per session. Do this 4 times over 2 hours.

No gluten window? Don't panic. My best loaves didn't pass that test. Focus on dough jiggle – it should wobble like Jell-O after final fold.

Shaping Secrets for Instagram-Worthy Loaves

Dust banneton heavily with rice flour (regular flour sticks). Shape dough tight by rotating toward center. Pinch seams closed. Seems fussy but prevents flatbread syndrome.

Confession: I still mess up shaping. If it unravels, reshape and rest 15 min. No shame in second tries.

The Bake That Actually Works

  1. Preheat Dutch oven at 500°F/260°C for 45 min
  2. Score dough 1/2" deep at 45° angle
  3. Bake covered 20 min
  4. Uncover, reduce to 450°F/230°C
  5. Bake 25 min until chestnut brown

That ear you see on pro loaves? Comes from shallow cuts. Go deep or go home. My first timid scores gave me sad flaps.

Why Your Sourdough Fails (And How to Fix It)

Problem Likely Cause My Fix
Gummy crumb Sliced too soon Wait 2+ hours after baking
Flat loaf Overproofed Reduce bulk time by 1 hour
Dense texture Underproofed Extend bulk 90 min next time
Pale crust Oven too cool Preheat 1 hour + use ice cubes

That dense loaf I mentioned? Underproofed. I was impatient. Now I set timers religiously.

Sourdough Starter Bread FAQs

Can I use starter straight from the fridge?

Technically yes... if you hate good bread. Feed it at least twice after refrigeration. Cold starter makes sluggish dough.

Why no commercial yeast?

You can add it, but then it's not real sourdough bread from starter. The whole point is wild fermentation.

My kitchen is cold – help!

Bulk ferment in oven with light on (temp ~78°F/25°C). Or use proofing box. I jury-rigged one from a cooler and warm water bottles.

How do I store leftover starter?

In fridge, fed weekly. Discard half, feed equal parts flour/water. Mine once survived 3 weeks – smelled boozy but revived fine.

My Pain-to-Gain Journey

Month 1: Edible only with soup. Month 3: Got compliments. Month 6: Friends offered to pay. Making sourdough bread from starter isn't quick, but that first perfect crust crackle? Worth every failed loaf.

Start today. Worst case? You get great breadcrumbs.
