This is hardly a recipe. This is a set of instructions for stuffing a prepared, frozen pastry sheet with seasoned mashed potatoes. While this sounds like a tasty dish, it is certainly NOT a knish. To call this a recipe for "New York" knishes is insulting. Authentic knishes don't use flaky prepared pastry dough. The recipe for knish pastry can be found on many sites. It is usually denser and more substantial than phyllo. If you are going to publish a recipe for stuffed phyllo, why not provide a recipe to prepare your own phyllo? If I have to go to the store to buy phyllo, I might as well look in the next freezer case and buy frozen knishes themselves. At least they might have an authentic taste and I won't have to make believe I'm baking. .
Sounds Good I will have to try it.
