What Is Scoring?
The Definition
Scoring is the act of cutting the surface of the proofed dough with a sharp blade (lame) immediately before baking. While often decorative, its primary function is mechanical: it creates a weak point for steam to escape and the bread to expand.
The Function
Without scoring, the rapid expansion of gas in the oven (oven spring) will cause the loaf to "blow out" at random weak spots, often ruining the shape. A functional score (like an ear) guides this expansion vertically, helping the loaf stand tall.

A lame (pronounced "lahm") is a baker’s tool consisting of a double-edged razor blade mounted on a handle. It is used for "scoring"—slashing the top of the proofed dough just before baking. It is not merely aesthetic; it is a surgical intervention to control expansion.
