Ingredients

Knish Dough

  • 2 cups flour
  • 2 teaspoons baking powder
  • 1 teaspoon salt
  • 1/4 cup vegetable oil
  • 3/4 cup apple juice or water

Potato Filling

  • 3 large potatoes
  • 1/2 onion
  • 1 egg
  • 1 egg for eggwash

Instructions 

  • Mix the dry ingredients
  • Add the vegetable oil and mix
  • Add 1/2 cup of apple juice or water and mix.
  • Add remaining liquid by the spoonful until dough is well-mixed
  • Cover and refrigerate the dough for 30 minutes or until ready to use.
  • While dough is chilling, boil 3 large potatoes in salted water.
  • Dice and sautee’ half an onion until translucent.
  • Place in a large bowl, mash the potatoes with a fork and season the potatoes with 2 tablespoons of evoo and salt and black pepper to taste.
  • Add the egg to the potato mixture and mix well.
  • Tip: I use an immersion blender to quickly puree the potato mixture, because my family prefers a smooth filling. Skip this step if you prefer otherwise.
  • Roll out the dough thinly into a rectangle.
  • Using a smooth edged knife, cut the dough in half vertically and then into quarter horizontally to make eight even-sized rectangles.
  • Add a dollop of potato mixture to the bottom half of a rectangle and fold and close the knish. Press the edges closed all around with your fingertips. (Like someone two-finger typing with their pointer fingers). Repeat with the remaining rectangles.
  • Brush each knish with beaten egg and bake on a parchment lined baking sheet for approximately 30 minutes.

Notes

Alternative:
Instead of potato, you can substitute tuna fish for the filling.
