Here's a follow-up to my series of slashing/proving experiments (sourdough.com/blog/slashing-and-crumbs).
Batch 1 - banneton proved. Slight break out on the diagonal slashed loaf. Definite difference made by the single legth-wise slash.
Crumb looks good - no mouse holes!
Batch 2 - couche proved.
2 with single length-wise slashes and 2 with triple diagonal slashes. Again, there's a difference between the sizes. And again, there's a breakout with the diagonal slash. Also, crackes at the tips of those loaves as well. It seems the dough can't contain itself when slashed this way. These loaves were proved for at least 8 hours.
ARG! Mouse hole! This is the crumb of the loaf seconf from right in the above photo.
UPDATE: tried the more diagonal slashes...
