Coney Knish Recipe

Place potatoes into a large pot and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until tender about 20 minutes. Drain and transfer to a bowl. Mash potatoes using a potato masher or a fork.

Preheat oven to 400 degrees F (200 degrees C). Grease a baking sheet.

Heat oil in a skillet over medium heat; saute onions until golden brown 10 to 15 minutes. Mix potatoes salt and pepper into onions. Remove skillet from heat and cool.

Roll each puff pastry sheet onto a work surface. Cut each sheet into 4 squares. Spread about 1/4 cup potato mixture onto each square in a strip down the middle; top with a hot dog. Cover each hot dog with about 1/4 cup more potato mixture. Roll puff pastry around hot dog and filling; place seam side-down on the prepared baking sheet. Brush puff pastry with egg.

Bake in the preheated oven until golden brown 10 to 15 minutes.
