How to Shape Sourdough into a Boule with Tight Surface Tension

You love the smell of baking bread, but your boules always spread instead of forming a neat dome. If you want a tight, glossy surface and a high oven spring, learning how to shape sourdough into a boule with tight surface tension is the missing step.

This guide shows exactly what you need and how to shape a boule step-by-step. You’ll learn simple motions, timing, and quick fixes so your dough holds its shape and looks pin-worthy. Read on to master shaping and get a bake-ready boule every time.

What You'll Need to Shape a Sourdough Boule

Gather these essentials before shaping:

• Tools: bench scraper, banneton or bowl lined with linen, dough scraper, and sharp scissors or lame.
• Ingredients: your fed sourdough starter, 500 g bread flour dough (approx. 65% hydration), extra flour for dusting.
• Timing: bulk ferment 3–5 hours at room temperature or until puffy; final proof 1–3 hours or retarded overnight in fridge.

Quick tips:

• Use a digital scale for consistent weights.
• Aim for 65–72% hydration for easier shaping if you’re new to this.
• Keep your hands lightly floured but not dry; tack helps create tension.

Getting Started: Prepare Your Dough for Shaping

Before shaping, do this:

• Gently turn dough out onto the floured surface. Handle it softly to preserve gas.
• Perform a quick preshape: fold dough onto itself to form a loose round. Rest 20–30 minutes under a damp towel (bench rest).
• This rest relaxes gluten and makes final shaping easier.

Why preshape matters:

• Preshaping builds initial strength without overworking.
• It helps you spot weak areas and adjust flour or tension during the final shape.

The Technique Step-by-Step: Forming a Boule with Tight Surface Tension

Follow these numbered steps to create strong surface tension:

1. Cup and Pull: Cup the dough with both hands. Use your fingers to pull the dough towards you across the surface, creating a smooth top. Repeat 3–5 times.
2. Rotate and Tuck: Rotate the dough 90 degrees, pull the edge, and tuck it under the loaf with each turn. Keep motions confident and even.
3. Tighten: Place the dough seam-side down. With cupped hands, drag the dough slightly against the work surface while turning it. This tightens the skin. Repeat until the boule feels like a taut balloon.
4. Seal and Rest: Pinch the final seam to seal air pockets. Dust lightly with flour and place seam-side up in a banneton or linen-lined bowl.

Timing and feel:

• The boule should feel springy and hold a slight dome. If it collapses, it was overworked or under-proofed.
• Final proof 45–90 minutes at room temp, or overnight in the fridge for a deeper flavor and easier scoring.

Pro tips:

• Use the heel of your hand for stronger pulls.
• Keep movements smooth; jerky tugs break the surface.
• For very wet dough, use a bench scraper to help tuck edges.

Troubleshooting and Storage: Fix Common Shaping Problems

If your boule spreads:

• Check fermentation: over-proofed dough won’t hold tension.
• Reduce hydration slightly (2–3%) if dough is unmanageably slack.
• Strengthen dough with an extra coil fold during bulk ferment.

If surface cracks or tears:

• Dough may be too dry on the surface—use a damp towel during proof.
• Try lighter pulls—tightening too quickly can cause splitting.

Storage and make-ahead:

• Bake same day after room-temp final proof, or retard in fridge up to 24 hours.
• Store cooled bread in a paper bag for 2 days, then freeze if longer preservation is needed.
