Used my Zo BB pac20 twice so far, both times the bread came out great, but the middle of the loaves sunk in. Any suggestions?
Occasionally my breads would sink because of over proofing. Try less yeast or reducing the proofing time, if you can control that.
That was happening to me on a regular basis with my machine. I reduced the amount of my yeast and the problem went away. I just got the newest model of the ZO, and am now experimenting with the recipes. I tried one from the instruction manual, same thing, so I will reduce the yeast IF I make that one again. It was pretty bland, but I only had unsalted butter, and did not think to increase how much salt I added, so that might be it. Am trying out my "go to" recipe for honey whole wheat and will see how that goes.
