Knishes can be purchased from street vendors in urban areas with a large Jewish population, sometimes at a hot dog stand or from a butcher shop. It is still strongly associated with the New York City region. It was made popular in North America by Ashkenazi Jewish refugees from the Pale of Settlement (mainly from present-day Belarus, Poland, Lithuania and Ukraine).
Knishes may be round, rectangular, or square. They may be entirely covered in dough or some of the filling may peek out of the top. Sizes range from those that can be eaten in a single bite hors d'oeuvre to sandwich-sized.
Ashkenazi Jewish immigrants who arrived sometime around 1900 brought knishes to North America. Knish (קניש) is a Yiddish word that was derived from the Ukrainian knysh (книш) and Polish knysz. The first knish bakery in America was founded in New York City in 1910. Generally recognized as a food made popular in New York City by Jewish immigrants in the early 1900s, the United States underwent a knish renaissance in the 2000s driven by knish specialty establishments such as the Knish Shop in Baltimore, Maryland, Buffalo and Bergen in Washington, DC, or My Mother's Knish, in Westlake Village, California.
