🥖 Mastered Crunchy Sourdough (Bakery-Level)

🔑 The 5 Secrets to a Crunchy Crust

1. Strong steam at the start

2. High hydration dough (70–78%)

3. Long cold proof (12–24 hrs)

4. Hot Dutch oven (preheated!)

5. Full bake — don’t underbake

🛒 Ingredients (1 large loaf)

• 500g bread flour (12–13% protein)

• 375g water (75% hydration)

• 100g active sourdough starter

• 10g salt

👨‍🍳 Step-by-Step Method

1️⃣ Autolyse (1 hour)

Mix flour + water until shaggy. Rest covered 1 hour.
(This builds gluten without kneading.)

2️⃣ Add Starter & Salt

Mix in starter and salt. Squeeze and fold until combined.

3️⃣ Bulk Fermentation (4–5 hours)

• Every 30 minutes for first 2 hours → stretch & fold.

• Let rest until dough is airy, jiggly, and ~50% risen.

4️⃣ Shape

• Pre-shape gently.

• Rest 20 minutes.

• Final shape with surface tension.

• Place seam-side up in floured banneton.

5️⃣ Cold Proof

Refrigerate 12–24 hours.
(This is where flavor + crust magic happens.)

🔥 Bake for Maximum Crunch

1. Preheat oven + Dutch oven to 500°F (260°C) for 45–60 minutes.

2. Flip dough onto parchment.

3. Score deeply (1 confident slash).

4. Bake covered at 475°F (245°C) for 20 minutes.

5. Remove lid, lower to 450°F (230°C), bake 20–25 more minutes.

6. For ultra-crunch → crack oven door last 5 minutes.

Internal temp should hit 205–210°F (96–99°C).

💥 Extra Crunch Boosters

• Spray dough lightly before baking.

• Add ice cube into Dutch oven when covered.

• Let loaf cool fully (at least 1 hour) — crust sets as it cools.
