I'm starting to think the potato bread bread wasn't as big a mistake as I first thought. I opened the oven to peek about 20 minutes after I put them in and they looked like they rose so fast they burst. They came out okay -- not super pretty, but decent and they taste great. Maybe my expectations were too high.
I've been irritable today. I think I'll go to bed early and read my book: Cruddy by Lynda Barry.
