I've made his Spanish tortilla once a month or so since that video came out... However, I once dropped the whole thing in the sink while doing the "flip". (Maneuvering a hot cast iron pan isn't easy.) I've never felt more disappointed in myself than I did at that moment; I was making it for breakfast and I basically just turned the stove off and went back to bed. So now I'm always a bit wary when I start on it, knowing that it has the power to destroy me psychologically.
