How to make delicious potato knishes

Step 1 : To prepare the knishes, first boil the potatoes until perfectly cooked, then mash them into a firm puree and set aside.

Step 2 : In a pot with oil and butter, brown all the finely chopped onions without seasoning.

Step 3 : Once ready, add the onions to the mashed potatoes, season with salt and pepper, and refrigerate the mixture.

Step 4 : In a mixing bowl, sift the flour and set aside, while in another bowl, mix the neutral oil, vinegar, eggs, warm water, and salt.

Step 5 : Gradually add the flour to the wet mixture, stirring with a spoon until a dough forms.

Step 6 : Divide the dough into 4 parts and let rest for 20 minutes.

Step 7 : Then, roll out each piece from the center outward with a rolling pin until very thin.

Step 8 : Place the cold filling 3 cm from the edge of the dough, in parallel to the longer side.

Step 9 : Roll the dough over the filling, giving 2 turns, and cut off the excess dough with a knife.

Step 10 : Next, cut and seal the knishes by pressing with your hand.

Step 11 : To give them the traditional shape, push the top inward to create a hole in the dough.

Step 12 : Brush each knish with egg yolk mixed with oil and bake on a greased baking sheet for 15 to 20 minutes over medium-high heat.
