Read your crumb
Your loaf is telling you something
Gummy
Underproofed or underbaked. Check bulk timing and bake temperature.
Dense
Weak gluten or a sluggish starter. Strengthen the dough, feed the culture.
Tunneling
Uneven shaping or a proof pushed too far. Tighten the preshape.
Pale crumb, flat loaf
Overproofed. Shorten the schedule for your kitchen temperature.
“A good crumb isn't luck. It's timing, temperature and a little feedback.”
