I desperately need help with crust. what I want is a paper thin, shatteringly crisp crust. but all I can achieve is moderately crisp but thick, hard, turtle shell crust. I have tried everything imagineable. dutch oven, cloche, steaming, misting absolutely everything I can think of. KA AP, Gold Medal AP, bread flour ..got desperate and yesterday I even used 1/2 C rice flour .. got the shattering part, but under it was 1/4 inch of turtle shell. (great rise and crumb) Fortunately my sandwich loaves are most always good. specially James Beard's sour cream bread. I'm still working on a satisfactory graham flour bread like I was raised on (70 years ago) Your help is appreciated ..
