Coney Island Knish Delight

Follow our step-by-step guide on how to make Coney Island Knish Delight.

1. Step 1

   To start your delicious knish journey, let’s prepare the dough.

2. Step 2

   In a large mixing bowl, combine flour, kosher salt, and baking powder, whisking them together until well blended.

3. Step 3

   Create a little well in the center and pour in the canola oil, warm water, beaten egg, and vinegar.

4. Step 4

   Using your hands, mix everything together until a dough forms.

5. Step 5

   Once it’s combined, transfer the dough to a floured surface and knead it gently until it becomes soft, smooth, and elastic.

6. Step 6

   Wrap the dough in plastic wrap and let it chill in the refrigerator for at least an hour—this will help it develop a lovely texture.

7. Step 7

   While the dough is chilling, it’s time to prepare the filling.

8. Step 8

   Start by placing your potatoes in a large pot, covering them with salted water, and bringing it to a boil.

9. Step 9

   Once boiling, reduce the heat to medium-low and let the potatoes simmer until they’re tender, which should take about 20 minutes.

10. Step 10

    After they’re cooked, drain the potatoes and transfer them to a mixing bowl.

11. Step 11

    Mash them up and set aside for later.

12. Step 12

    Next, chop the corned beef and cabbage into small pieces.

13. Step 13

    In a large skillet, melt some butter over medium heat.

14. Step 14

    Add the chopped onion, corned beef, cabbage, and a pinch of kosher salt.

15. Step 15

    Cook this mixture, stirring frequently, until the onions turn soft and golden brown, and the beef fat has rendered, which should take around 10 minutes.

16. Step 16

    Once done, transfer this savory mixture to the bowl with the mashed potatoes.

17. Step 17

    Season it with cayenne pepper, salt, and black pepper, mixing everything together until well combined.

18. Step 18

    Allow the filling to cool to room temperature—this will make it easier to work with later.

19. Step 19

    Now, let’s get your oven preheating to 375°F (190°C) and line two baking sheets with silicone mats to prevent sticking.

20. Step 20

    Take the chilled dough and divide it in half.

21. Step 21

    On a floured surface, flatten one half into a rectangle and roll it out to about 1/8-inch thick, pulling the corners gently as needed to maintain the shape.

22. Step 22

    Spread about 3 cups of your delicious filling along one long edge of the dough, leaving a 3-inch border on the sides.

23. Step 23

    In a small bowl, beat the remaining egg with a splash of water to create an egg wash.

24. Step 24

    Brush this egg wash over the opposite end of the dough and a bit on the sides to help seal everything together.

25. Step 25

    Carefully stretch the dough to cover the filling, then roll it up towards the egg-washed side.

26. Step 26

    As you roll, fold the last 3 or 4 inches of dough over the top, pressing the filling in as you go.

27. Step 27

    Once rolled, place the seam side down.

28. Step 28

    If you have any excess dough at the ends, feel free to trim it off.

29. Step 29

    Lightly mark the dough into 8 equal pieces without cutting all the way through.

30. Step 30

    Flour your hands and press into the marks, then rub back and forth against the counter to separate each piece.

31. Step 31

    Position each piece with one cut end facing down and the other facing up.

32. Step 32

    Gently squish down the top and tuck everything into the center to form a lovely round knish.

33. Step 33

    Repeat this process with the remaining dough and filling.

34. Step 34

    Brush the bottoms of the knishes with olive oil and place them on your prepared baking sheets.

35. Step 35

    If you have any leftover egg wash, brush it on top of the knishes for a beautiful golden finish.

36. Step 36

    Now it’s time to bake! Place the knishes in your preheated oven and let them bake until they’re lightly golden brown, which should take about 40 minutes.

37. Step 37

    Once they’re done, allow them to cool until they’re just warm or to room temperature before serving.

38. Step 38

    Enjoy the delightful flavors of your homemade knishes, perfect for sharing with family and friends!.
