Scoring
Cutting the surface of a proofed loaf so it opens where the baker chooses rather than bursting where the crust happens to be weakest.
A loaf entering a hot oven expands rapidly before its crust sets. That expansion has to go somewhere, and if the surface is intact it will tear at whichever point is weakest — usually a seam, and usually somewhere unwanted.
Scoring makes a deliberate weak point. The cut opens as the loaf expands, giving the characteristic ear on a well-scored loaf and, more importantly, preventing the ragged blowout on the side that an unscored lean loaf tends to produce.
The angle matters more than the depth. A shallow cut made almost parallel to the surface lifts a flap of dough that curls back as it bakes, producing an ear. A vertical cut of the same depth simply opens into a valley. Neither is wrong; they are different results from the same tool.
Scoring is much less important on enriched and tinned loaves, where the dough is softer and the tin constrains the expansion — which is why a sandwich loaf needs no score and a baguette badly needs one.
What it is for
To control where a loaf opens during oven spring, rather than allowing it to burst at an unpredictable weak point.
Uniform professional practice with an obvious mechanism. Recorded as convention because no measured study of scoring geometry was consulted.

How to tell it has worked
- The blade passes through the surface without dragging or sticking.
- The cut stays open rather than closing behind the blade — a cut that closes indicates over-proofed dough.
- During the bake the score opens and lifts rather than merely widening.
What it changes
| Property | Effect | Why |
|---|---|---|
| Volume | Increases | A loaf that vents where it was scored expands more fully than one restrained until it tears. |
| Crust | Changes | The opened cut exposes soft interior that browns differently from the set surface. |

Scoring decides where the loaf opens. On a baguette it is not decoration — an unscored baguette bursts at a random weak point.
