Ear

An ear is the thin, curling flap of crust that peels upward along a scored line as a loaf springs in the oven. It forms when a confident, angled cut with a lame lifts a flap of dough surface that then catches steam and expands independently of the rest of the crust, browning into a crisp, slightly separated ridge.

Bakers often treat a well-formed ear as a visual marker of good technique because it depends on several things lining up at once: a properly proofed dough with enough gas left to expand, a sharp blade making a clean, shallow-angled cut, and enough steam in the oven to keep the flap flexible long enough to lift before the crust sets. A missing or flat ear usually points back to one of those factors rather than any single mistake.

A sharp lame and a steamy baking setup are the two things most directly tied to getting a strong ear. A common mistake is scoring too deep and too straight down, which cuts through rather than lifting a flap; a shallow angle, closer to the surface, generally produces a cleaner ear. Under-proofed dough can also produce an exaggerated, sometimes uneven ear compared to a well-timed bake.
