Only in New York can you get a true history of the knish, immigrant food which has filled menus and hungry stomachs for generations. Journalist Laura Silver is giving a FREE lecture on the life and times of the knish, from its origins in Eastern Europe to NYC icon. Whether it’s filled with potato, kasha, cheese or veggies, the knish has become a NYC native, much like hot dogs and tacos, which also arrived with immigrants. Baked or fried, round or square, sweet or savory, Silver tells stories from her new book, The Book of Knish. The free lecture is 6:30 p.m. Tuesday, August 7th, at the Mid-Manhattan branch of the New York Public Library. That’s the one across the street from the main branch with the stone lions out front. The best knish store in city, of course, is Yonah Schimmel’s Knish Bakery on East Houston Street, where they’ve stopped counting how many millions of knishes they’ve baked and served since opening in the early 1900s.
