Scoring is not decoration — it is structural control. A proper score directs oven spring upward, prevents blowouts, and creates a dramatic ear and bloom.

1. Why We Score Sourdough
During baking, trapped CO₂ expands rapidly. As the crust begins to set, pressure builds. Without a controlled weak point, the loaf will burst randomly.
- Scoring creates a planned expansion path
- Encourages upward oven spring
- Forms a lifted crust flap (the “ear”)
- Improves loaf symmetry
- Prevents side blowouts
Think of scoring as telling the loaf exactly where to open.
2. Tools You Need
Lame (Razor Tool)
The most precise tool for clean scoring.
Straight Blade
Creates more vertical openings.
Curved Blade
Best for strong ears and dramatic bloom.
Knife (Not Recommended)
Too thick; drags dough and causes jagged cuts.
Optional: lightly oil the blade for sticky dough.
3. When to Score
Score right before baking, after final proof.
Best results occur when:
- Dough is properly proofed (30–50% rise)
- Surface tension is strong
- Dough is slightly chilled from the refrigerator
If unsure about proof level, review: How to Know When Your Dough Is Ready
Under-proofed dough resists scoring. Over-proofed dough collapses when cut.
4. The Perfect Scoring Angle (30–45° Rule)
Blade angle determines whether you get a pronounced ear.
- 30–45° angle: Creates a thin flap that lifts into an ear
- 90° vertical cut: Opens flat with little ear
Angle matters more than depth.
5. How Deep to Score
Standard depth: ¼ inch (6 mm)
- Too shallow → score seals shut
- Too deep → loaf spreads and weakens
- High hydration → may need slightly deeper cut
Strong shaping tension improves scoring performance. Review shaping here: Shaping Guide
6. The Classic Single Slash (Best for Beginners)
- Place loaf seam-side down
- Hold blade at 30–45°
- Start near the top third of the loaf
- Sweep downward in one confident motion
- Do not saw back and forth
The cut should resemble a lid that can peel back during baking.
7. Simple Scoring Patterns
Beginner Functional Patterns
- Single long slash
- Crescent slash
- Double parallel slash
Decorative Patterns (Intermediate)
- Wheat stalk
- Leaf pattern
- Crosshatch
- Starburst
Functional scoring ensures proper expansion. Decorative scoring should never restrict oven spring.
8. Troubleshooting Scoring Problems
No Ear Forms
- Blade too vertical
- Dough over-proofed
- Weak shaping tension
Loaf Bursts on the Side
- Score too shallow
- Seam not sealed
- Uneven shaping tension
Blade Drags
- Dough too warm
- Blade dull
- Dough over-proofed
Score Seals Shut
- Under-proofed dough
- Cut too shallow
- Insufficient steam during baking
9. Pro Tips for Better Ears
- Score cold dough straight from the fridge
- Use a curved razor for stronger ears
- Maintain strong shaping tension
- Use steam in the first 20 minutes of baking
- Make one smooth, confident cut
A strong ear is a combination of:
- Proper fermentation
- Correct shaping
- Proper blade angle
- Sufficient oven steam
10. FAQ
Can I score without a lame? Yes, but results are less consistent.
Should I flour the loaf before scoring? Light flour helps decorative contrast.
Why does my score look jagged? Blade dull or hesitant motion.
Can I score with scissors? Yes, especially for decorative high-hydration cuts.
Why does my loaf deflate when scored? It is over-proofed.
