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.
