Make the Potato Filling

1. Gather the ingredients.

   

2. In a large bowl, mix together the cooked and shredded potatoes, sautéd onions, eggs, instant mashed potatoes, salt, ascorbic acid, if using, garlic powder, Tabasco sauce, and cheddar cheese, if using. Adjust the seasoning with salt to taste.

   

3. Mix until thoroughly combined. Set aside.

   

Assemble the Knishes

1. Gather the ingredients. Position 2 racks in the upper and lower part of the oven and heat the oven to 350 F.

   

2. Flour a work surface and place the dough on it. Cover the dough with plastic wrap and let come to room temperature, 15 to 20 minutes.

   

3. Roll the dough to a rectangle that is 1/4-inch thick. Using a pizza cutter, cut the dough into 3-inch squares. Re-roll any remaining dough scraps until all the dough is used.

   

4. Make the egg wash by combining the beaten egg with 1 tablespoon water and 1 drop of yellow food coloring, if using. Brush each square with the egg wash.

   

5. Place about 2 tablespoons of filling on each square. Then fold the corners to meet in the middle, similar to an envelope, pinching the edges closed.

   

6. Place the knishes on a two parchment lined baking sheets and brush with more egg wash. Continue with the rest of the dough and filling.

   

7. Bake the knishes for 30 to 35 minutes, rotating the pans half-way through baking until they are golden brown on the top and bottom.
