When it goes wrong · Score
The bread burst along its side instead of opening at the cut.
Can you save it?
Reviewed for this symptom
It bakes perfectly well — the burst is cosmetic. Let it cool fully before slicing, and if you want it presentable, serve it burst-side down. Score deeper and check the proof next time.
How to confirm the diagnosis
Observable cues, not inferred user state
- A tear along the side or base while the scored line barely opened
- The cut was very shallow
- The dough had spread or looked slack going in

What actually happened
Only this symptom
Scored too shallow, or the dough was over-proofed and had no oven spring left to direct.
The full mechanism
Shared by every score failure
Scoring is nearly always about controlling something that is going to happen anyway. Skin and fat contract when heated and will tear somewhere; scoring decides where, and opens channels for rendered fat to escape rather than pooling under the skin. Bread does the same thing under gas pressure — a loaf expands violently in the first minutes of baking and will burst at its weakest point, so a deliberate cut gives the expansion somewhere to go and the loaf keeps its shape instead of splitting along its side. On squid and kidneys, scoring shortens the muscle bundles so the piece curls rather than toughens. And on anything being marinated, shallow cuts increase surface area, though only marginally — a marinade still penetrates a few millimetres at most, and scoring does not change that fact as much as recipes imply.
The full Score lesson — how to tell, where to practise it, what it carries to.

Prevent this specific failure
Score about a centimetre deep with a sharp blade at a shallow angle, and bake before the dough is over-proofed and slack.
What right looks like
Shared by every score failure
- Cuts go through skin and fat but stop at the flesh — you should feel the resistance change.
- On bread, the cut is shallow and angled rather than vertical, so a lip forms and lifts as it bakes.
- Scored fat opens visibly within the first minutes of heat as it contracts.
- The blade must be very sharp; a dull knife drags the skin rather than parting it, especially on wet dough.
