From grimoire
Designs bread scoring cut patterns, blade angles, and depth to control oven spring and crust formation. Useful when scoring sourdough or enriched doughs before baking.

Score bread loaves with planned cut patterns at the correct angle and depth to direct oven spring, prevent blowouts, achieve consistent ear formation, and produce decorative surface results.

Adopted by: Scoring is mandatory in professional artisan bread production. The Bread Baker's Guild of America and Maison Poilâne (Paris) both treat scoring as a foundational skill requiring pattern design before application. Jeffrey Hamelman's "Bread" — the standard bakery reference — dedicates significant coverage to scoring theory and blade technique. Competition bread judging criteria (Coupe du Monde de la Boulangerie) explicitly assess scoring quality, ear development, and symmetry. Impact: Unscored bread or poorly scored bread "blows out" — the steam from the interior finds the weakest point in the crust (usually a seam or crack) and bursts unevenly. A properly designed score provides a deliberate expansion channel, directing spring where desired, creating the ear (the raised flap of crust along the cut), and producing the characteristic "open crumb" of artisan bread.
The score controls the expansion of the loaf during the first 10–15 minutes of baking ("oven spring"):
Lame (curved razor blade on a handle): standard for sourdough boules and batards; allows shallow-angle cuts without dragging
Razor blade (on a dowel or lame stick): same as lame; common for beginners
Sharp serrated knife: acceptable for lower-hydration doughs (brioche, pullman loaves); drags on high-hydration sourdoughs
High-hydration doughs (75%+) require a very sharp, thin blade and a decisive quick cut — dragging a blade through sticky, high-hydration dough compresses the gas cells and deflates the loaf.
Sourdough boule (round):
Sourdough batard (oval):
Baguette:
Pullman/sandwich loaf:
Cold dough scores better: refrigerating the shaped loaf overnight (retard proofing) firms the surface; a cold, firm dough holds the cut shape while a warm, soft dough drags and compresses.
Technique:
Test: before scoring the final loaf, practice the motion on a folded piece of paper — the same drawing motion. Score should be confident and linear.
| Outcome | Cause | Fix |
|---|---|---|
| Blowout (tear on side) | Score too shallow; dough under-proofed | Deeper score; extend proof time |
| Score closes without opening | Over-proofed dough; gas cells exhausted | Reduce proof time; score more aggressively |
| Dragged/torn cut | Blade not sharp; dough too warm | Fresh blade; colder dough |
| No ear formation | Blade angle too steep (perpendicular) | Angle blade flatter (15–30°) |
| Uneven ear | Inconsistent blade depth | Practice; one smooth continuous stroke |
Scoring works in conjunction with steam in the oven:
