Being a New York Jew, one of the foods you eat with your mother’s milk is a potato knish. (A client from Chicago named her cute little Labrador mix Knish.) A very thin pastry filled with tasty seasoned mashed potatoes. The BEST knish in the universe is at Yonah Schimmel’s Knishery, conveniently located on Houston down the street from Katz deli. You walk in and get one right out of the oven and eat it walking down the street. My mouth is watering just thinking about it. Go!
