Here’s a detailed homemade fluffy sourdough challah recipe that gives you a soft, slightly sweet, golden braid with a gentle tang from natural fermentation. It’s a bit of a time project (like most sourdough breads), but the texture is worth it.

🥖 Fluffy Sourdough Challah (Soft & Rich Braided Bread)

Challah made with sourdough is lighter in sweetness than commercial versions, with a deeper flavor and extremely soft crumb.

🧾 Overview

• Prep time: 30–45 min
• Fermentation: 8–14 hours total (flexible)
• Bake time: 30–35 min
• Yield: 1 large challah (or 2 medium)

---

🌾 Ingredients

Levain (optional but recommended for better rise)

• 50g active sourdough starter (100% hydration)
• 50g flour (bread flour or all-purpose)
• 50g water

Main Dough

• 450g bread flour (or strong all-purpose flour)
• 100g active sourdough starter (or all levain)
• 2 large eggs + 1 yolk (reserve white for wash)
• 120g warm water or milk (milk = softer crumb)
• 60g sugar or honey
• 8g salt
• 60g unsalted butter (softened)
• Optional: 1 tsp vanilla (for slight sweetness)

Egg Wash

• 1 egg white + 1 tbsp water (or whole egg for richer color)
• Sesame or poppy seeds (optional topping)

---

🧠 Step 1: Prepare the Levain (Skip if using active starter directly)

Mix and let it rise 4–6 hours until doubled and bubbly.

You want it:

• airy
• domed top
• slightly sweet-smelling

---

🥣 Step 2: Mix the Dough

1. In a large bowl, combine:
   • starter or levain
   • eggs + yolk
   • water/milk
   • sugar/honey
2. Add flour and mix until no dry spots remain.
3. Rest (autolyse) for 30–45 minutes.
4. Add:
   • salt
   • softened butter
5. Knead 8–12 minutes until smooth and elastic.

👉 Dough should be:

• soft
• slightly sticky but workable
• stretchy (windowpane stage)

---

⏳ Step 3: Bulk Fermentation (First Rise)

Cover and let rise:

• 6–10 hours at room temp (22–26°C)
  OR
• Overnight in a cooler environment

During the first 2–3 hours:

• Do 2 stretch-and-folds (optional but improves structure)

You want:

• dough doubled in size
• airy and jiggly

---

✂️ Step 4: Divide & Shape

1. Turn dough onto a lightly floured surface
2. Divide into:
   • 3 strands (classic braid) or
   • 4 strands (more decorative)
3. Pre-shape into balls and rest 15 minutes
4. Roll each into long ropes (30–40 cm)

---

🧵 Step 5: Braid the Challah

Classic 3-strand braid:

• Left over middle → Right over middle → repeat

Keep it slightly tight but not stretched too thin.

Place on parchment-lined tray.

---

🌙 Step 6: Final Proof

Cover and let rise:

• 3–5 hours at room temp
  OR
• overnight in fridge (better flavor + easier handling)

Ready to bake when:

• puffy
• slightly jiggly when shaken
• indentation slowly springs back

---

🔥 Step 7: Bake

1. Preheat oven to 180°C (350°F)
2. Brush with egg wash
3. Bake:

• 30–35 minutes total

Optional:

• Rotate tray halfway for even color

---

🌟 Done when:

• deep golden brown crust
• internal temp ~93°C (200°F)
• sounds hollow when tapped

---

🧈 Step 8: Cooling

Let cool at least 1 hour before slicing.

(Hot challah tears instead of slicing cleanly.)

🧁 Tips for Extra Fluffy Texture

• Use milk instead of water → softer crumb
• Add yolk-heavy dough → richer texture
• Don’t over-flour during shaping
• Slightly under-proof rather than over-proof
• Use a strong, active starter (peak activity matters)

---

❄️ Storage

• Room temp: 2–3 days wrapped
• Freezer: up to 2 months (slice before freezing for convenience)

---

🍯 Optional Variations

• Raisin cinnamon swirl challah
• Honey glaze instead of egg wash
• Sesame + black seed topping
• Chocolate chip enriched version
