Last night on Throwdown, Miriam made pickled red onions for a hot dog challenge Bobby was doing. I could swear she said she left them sit overnight. had turned a beautiful shade of purple. I've been craving them ever since a recent trip to LA. What she made seemed closest to what I'm looking for but when I googled it, the Bobby Flay pickled red onion recipe looks completely different. Does anyone have a good recipe?
