Bread-Bakers v102.n057.14

Hello!
I am a bread baker with a problem! I make bread using Spelt flour. Often, 
but not always, I have "caves" in the center of my loaves. I cannot figure 
out the reason for these holes. Does anyone have any ideas? I make all of 
our beread, and I'm getting tired of the "hole-in-the-middle" syndrome!

Thanks,
Kay Greene
