The Knishwich

Tom Pizzica builds the "Ultimate New Yorker" at Lansky's Deli in New York, a seven-pound deli sandwich with corned beef and pastrami packed between a potato knish instead of bread. At Feast in Houston, Texas, he tries heart, black pudding and pig face at this "nose to tail" joint. For dessert, Tom heads to Dania Beach, Fla., where a crowd of school kids help make and taste the jumbo-sized sundaes served at Jaxson's Ice Cream Parlor.
