The center loaf has overlapping cuts
Why might a baker score boules with slashes that are wider or deeper than normal?
To accommodate underproofing and prevent a blowout

It is both tedious and time-consuming
What is the result of careless scoring or an ineffective pattern?
A compressed crumb structure
What is the effect of scoring a loaf with a 'sausage cut'?
The loaf blows out noticeably
Why might a baker need to adjust their scoring technique in a real-world bakery production?
To deal with underproofed or overproofed loaves
What is the main difference between the loaf on the left in Figure 8.1a and the loaf on the right?
The loaf on the left has been scored with a straight cut
What is the purpose of scoring a loaf?
To relieve pressure inside the loaf and control expansion

When a loaf breaks open in an unattractive way
Study Notes
Scoring Loaves
- When loaves are loaded into the oven, they undergo a brief stage of dough fermentation, and yeast cells ferment the dough in an accelerated fashion, generating a large amount of CO2 gas.
- This phenomenon is known as oven spring, causing sudden growth in the loaf and tremendous pressure on its exterior.
- If the loaf is not scored, the intensely dry heat of the oven can form a skin that restricts its ability to expand, resulting in a tighter crumb and possible distortion or rupture.
Purpose of Scoring
- Scoring helps the loaves grow in a controlled, attractive manner and ensures an open crumb structure.
- It coaxes the intense gas pressure in the direction desired, allowing the loaf to expand fully without rupturing.
Types of Scoring
- Not all loaves require scoring, such as pan loaves, which are surrounded by the pan and can expand fully without rupturing.
- Scoring can be done with a straight cut, a diagonal cut, or a cross shape, depending on the type of loaf and desired outcome.
Importance of Scoring
- Scoring can make a significant difference in the volume, crumb structure, and overall attractiveness of the loaf.
- If scoring is done carelessly or the pattern used doesn't relieve enough pressure, the bread takes on a distorted shape, limits its expansion, and creates an unappealing exterior appearance.
- Appearance is important, as customers often avoid distorted loaves, even if their eating quality is fine.
Factors to Consider
- Scoring should be adjusted based on the proofing level of the loaf, with underproofed loaves requiring wider or deeper cuts to accommodate further growth.
- Scoring may not be necessary for small rolls, which expand quickly and may not require controlled growth.
- Time and cost considerations should also be factored into the decision to score loaves or rolls.
