Earlier this year when I was in New York I visited Veselka for the first time. They specialize in Ukranian food, but I was there for one thing: pierogi. Their pierogi were some of the best I've ever had. Veselka has a cookbook out, but I don't have it (yet) so I found their recipe online and promptly made some of my own pierogi. My version is stuffed with cheese, potatoes and caramelized onions.
