Ruth Bourdain, the Beard Award-winning parody Twitter account/mashup of Anthony Bourdain and Ruth Reichl, has kept his/her anonymity locked up tight, but Lee Svitak Dean over at the Star Tribune's Table Talk blog is making the call: "Ruth Bourdain = Robert Sietsema, food critic for the alt-weekly Village Voice in New York City."
Wrote Dean: "How do I know who Ruth Bourdain is? He was tweeting while listening to the same speaker I was, in a closed room in Charleston, SC, at a conference with the Association of Food Journalists."
Update 11:25am: Sietsema told Eater: "I could do better humor wise. And don't forget Ruth was my patrón."
