<<Disclaimer: Verify this information before applying it to your situation.>> Hi I just made Pilgrim South's bread recipe. It actually worked out better than most homemade breads with one problem. After taking it out of the oven, the center sinks down about 1/2 - 1". I am using a medium bread pan (I used to use the large loaf pans but always had the center drop down to about a 1/2" height - and heavy like a pound cake). Any idea what I am doing wrong? Shelly
