Now who doesn't love a good knish- an no the 'k' isn't silent. It's pronounced "Ke-Nish".
Knishes, not to be confused with Kamish (which is a cookie) or Kanadalech (Jewish slang for testicles) Knishes are an Eastern European/Jewish dumpling kind of snack. Leave it to the Yigs to mix together white potato, white flour, fill it with cheese and onions fry it in chicken fat and top it with sour cream and call it a 'snack'. The true definition of a knish is simply a filling covered with dough that is either baked, grilled, or deep fried.
Many cultures have variations on baked, grilled, or fried dough-covered snacks similar to the knish: the Cornish pasty, the Scottish Bridie, the Jamaican patty, the Spanish and Latin American empanada, the Portuguese rissole, the Italian calzone, the South Asian samosa, the Russian pirozhki, and the Middle Eastern fatayer to name a few.
