I'm in Atlanta, where it is very humid, and I've tried twice now to make the Lahey/Bittman loaf. It only rises about halfway. The dough is much stickier than when I made it in Chicago. Could it be the humidity? What do I do? Increase the 1/4 tsp of yeast to 1/2? Add more flour? I have no idea. It's the only bread I've ever made that turns out perfectly every time. Until now.
