Crusty film on my proofed bread
Hello,
I'm about a month new to sourdough bread. I've had pretty decent success so far, however, I have run into the same crusty film each time.
This film forms over the top of the levain, and I just stir it back in. No biggie. It then forms on the top of my loafs during their final proof overnight in the fridge, making slashing the top difficult, as the film catches on the knife and moves the whole top of the bread. The bread also doesn't break open like I'd expect.
Is there something I can do differently? Where am I going wrong?
