Scoring troubleshooting

Why sourdough does not open or form an ear

An ear depends on fermentation, shaping, dough temperature, steam and the score working together. Treat the bake as evidence: first identify where the loaf expanded, then change one variable on the next loaf.

Start with what happened

Bake resultCheck firstNext experiment
The score sealed and the loaf stayed lowOver-proofing, weak dough or a slow/shallow cutScore immediately before baking and compare a slightly shorter final proof.
The loaf burst at the side or baseThe intended score did not provide enough expansionMake one clear main score and confirm adequate early steam.
The score opened evenly but made no flapBlade orientation and surface tensionTry a shallower blade angle while keeping the line decisive.
The loaf had little oven spring anywhereFermentation and dough strength before scoringFix fermentation/shaping before chasing a decorative ear.

Encourages a direct opening and is useful for many decorative cuts.

Can leave a flap that lifts into an ear when the dough and bake are ready for it.

Control the test

  • Use the same recipe and loaf shape for comparison.
  • Score immediately before loading the oven.
  • Use one committed motion instead of sawing repeatedly.
  • Keep decorative cuts shallower than the main expansion score.
  • Record proof time, dough temperature and result.

Razor blades are extremely sharp. Stabilize the loaf, keep fingers out of the blade path, and cover, remove and dispose of blades safely.
