Round Shaping (Formen Rund) โ€“ Sourdough Shaping Technique

How to shape a tight round loaf (boule) for even crumb, surface tension and strong oven spring. Step-by-step practical guide for home bakers.

Why This Technique?

Creates surface tension and a compact outer skin that traps gas for better oven spring and an even crumb.

Round shaping (forming a boule) tightens the dough surface and concentrates strength in a cohesive skin. That surface tension contains fermentation gases and directs expansion upward during oven spring rather than sideways, producing higher loaves with even crumb distribution. Proper shaping also redistributes gas and equalizes dough temperature immediately before final proof, which improves predictability [1][2].

โœ“ Improved oven spring and higher loaf โœ“ Even crumb with fewer large voids โœ“ Predictable shape for scoring โœ“ Cleaner presentation and easier handling

When to Use

โœ“ Suitable for:

  • โ€ข After bulk fermentation when dough has some strength and extensibility
  • โ€ข High- to medium-hydration wheat doughs (55โ€“80% hydration)
  • โ€ข When you want a tight skin for scoring and oven spring

โœ— Not suitable for:

  • โ€ข Very slack, extremely high-hydration doughs (>85%) โ†’ Dough cannot hold tension; use a gentle Coil Fold or basket-style shaping
  • โ€ข Pure rye or very low-gluten doughs โ†’ Insufficient gluten to form a strong skin

Step by Step

Preparation:

Lightly flour your work surface and have a [dough scraper/bench knife (OXO)](https://amzn.to/3LR1f5E) and a [banneton proofing basket](https://amzn.to/4sNHBYO) or floured bowl ready. Weigh ingredients and dough stages on a [Digital Kitchen Scale](https://amzn.to/4pUMVHi) for consistency.

1

Pre-shape: Turn the dough out onto a lightly floured surface and use a dough scraper/bench knife (OXO) to gently fold edges into the centre, creating a loose round.

๐Ÿ‘€ A soft, slightly tightened ball with visible seams on the underside.
2

Bench rest: Let the pre-shaped dough rest 15โ€“30 minutes uncovered (prevents over-flouring and allows gluten to relax).

๐Ÿ‘€ Dough surface relaxes and becomes tacky but not sticky.
3

Final shaping โ€” tighten the boule: Cup your hand over the dough, drag it toward you across the work surface with slight downward pressure so the underside stretches and creates tension on top. Rotate 90ยฐ and repeat 6โ€“8 times until the surface is taut.

๐Ÿ‘€ Smooth, tight top surface; seam on the bottom.
4

Create a clean seam: Flip the dough seam-side down and use the scraper to tuck in any loose edges, forming a tidy base that will hold when inverted into a banneton proofing basket.

๐Ÿ‘€ Neat, sealed seam; boule holds shape when lifted.
5

Proof: Transfer seam-side up into a floured banneton proofing basket or bowl. Cover and proof to desired poke-window (test explained below).

๐Ÿ‘€ Dough fills the basket; surface retains tension for scoring.
6

Transfer and score: Invert gently onto a piece of parchment paper (Katbite) or directly into a heated Dutch oven (CRUSTLOVE). Score with a bread lame/scoring tool (SAINT GERMAIN) to control expansion.

๐Ÿ‘€ Clean, decisive slash; loaf ready for oven.

How Often?

Shaping happens once after bulk fermentation (pre-shape + final shape). Avoid multiple full re-shapings to prevent degassing.

How do I know it's enough?

When the surface is smooth and resists gentle pokes (pokes spring back slowly) and the dough holds its shape when lifted, tension is sufficient. If dough collapses or feels loose, it needs a gentler re-tighten or longer rest before final proof [1][2].

Common Mistakes

โŒ Over-handling and re-shaping repeatedly

Problem: Degasses dough, reduces oven spring and creates dense crumb

Solution: Limit to one pre-shape and one final shaping; handle gently and decisively

โŒ Excess flour on the surface

Problem: Prevents seam adhesion and weakens tension

Solution: Use minimal flour; dust only where necessary and use a [jar spatula (U-Taste)](https://amzn.to/3ND05v5) or scraper to clean excess

โŒ Shaping when dough is too cold or too warm

Problem: Cold dough tears; overly warm dough becomes slack

Solution: Aim for dough at room temperature and use a brief bench rest to relax gluten if needed [1]

โŒ Not creating a clean seam

Problem: Seam opens during final proof or baking, causing odd shapes

Solution: Tuck and seal the seam firmly during final shaping; place seam against the basket so the top is smooth
