The recipe is from Food and Wine Magazine. It's by Spike Mendelsohn, who was on a recent-ish season of Top Chef. He drove me nuts on the show (seriously, dude, don't talk back to Tom Colicchio), but after seeing his food in F &W and trying out this recipe I actually want to buy his new cook book. If that's not an endorsement for you to try that recipe, I don't know what is. As you know, I can be a little judgmental.
