Chef/Owner Matt O’Neil of The Blue Ox cooks up his stand-out “Sin Burger” at the 8th Annual Amstel Light Burger Bash in Miami, Florida. The burger (named for Lynn, Lynn City of Sin, of course!) was one of 31 burgers to compete for Best Burger to be judged by celebrities such as Rachel Ray. They were the only Massachusetts restaurant at the competition and made it to the second round at last night’s event. The “Sin” Burger, which is on the menu at The Blue Ox, is hand packed by Chef Matt O’Neil every night and features 100% USDA prime beef, applewood smoked bacon, Swiss cheese, truffle aioli, lettuce and tomato and is served on a brioche bun.
