Cheese Blintzes, (called Cheese Blintz, Cheese Blintze, Blintz, or Blintze) are thin flour crepés folded to form a casing for cheese and then sautéed to a golden brown and served hot, hot, with sour cream. A blintze is a thin crepe-like pancake filled with cheese. Blintzes are pretty easy to make, and they’re one of the most delicious things EVER (in my humble opinion). If you’ve never made a blintz, this is your day to have one. Blintzes are filled and folded pancake that goes by the name blintze is thought to have originated in Central Europe…Poland, Hungary, Slovakia, that general area.
