Okay, lately I've been catching a new smell when I smell baked goods. The clincher was this morning when I drove across town to get some Mexican pastries from La Estrella, one of our favorites, and I smelled this awful smell that I'd never smelled there that I smell near a Subway, and it really threw me for a loop- nearly ruined the whole experience. It's something that seems to go with leavening (not 100% on that)- what the heck is it? An awful sickening almost funereal smell where there should be the scent of leavening Mexican pastries. It freaked me out.
