When is a restaurant that serves bacon considered kosher? To most Orthodox rabbis, the answer is easy: never. But Staten Island rabbi Dov Hazdan has been granting his own kosher certification to city Dunkin’ Donuts franchises that have served bacon, ham, and sausage, the trayf trifecta. “The meats all come prepackaged,” says Hazdan. “The employees have to wear gloves. I do not condone mixing kosher with nonkosher.” In Manhattan, Hazdan has also given his ner tamid K stamp to Pongal Vegetarian, an Indian restaurant that operates during the Jewish Sabbath, another no-no among the pork police. Hazdan was recently fired as the kosher supervisor at a Dunkin’ franchise on 34th Street after it received complaints from the Yeshiva University community about the rabbi and the pork. Spokesmen for the four top kosher-certifying agencies said they would never approve a restaurant that served nonkosher meats or operated on the Sabbath. “Who knows what goes on behind the counter?” says one Staten Island rabbi of Hazdan-approved shops. Hazdan insists his methods are 100 percent kosher. “I know a lot of people with beards who go into my stores,” he says. Next: The Fly Life Comes to ESPN2!
