Tried three times, but I couldn't get any of my dough to rise - today, of all days.

Update: Rather than toss it in the trash with the others, I put my third batch of dough into a sarcophagus of stainless steel, then locked it in a cold dark cave, hoping for a miracle. And when I checked it, hours later... lo, it had risen!. And I baked it! And 45 minutes later, there was a nearly-perfect French boule on my counter top! My first successful loaf of bread, ever - the last of six attempts in the past 8 days. And we ate four slices of that steamy fresh French bread it as soon as it was cool enough to handle. Even though it was 10:30 at night. The very middle wasn't quite cooked enough, so I popped the whole loaf back into the oven - instead of putting it into the covered Dutch oven it had come out of. Five minutes later, the top was burned to black. Alas! Well, at least I got four heavenly slices out of it.

Thank you, Michael Ruhlman (and your bread-baking app)!
