Making Reuben Balls with Spicy Thousand Island Dipping Sauce is straightforward if you follow these simple steps:

1. Prepare the Filling: In a large bowl, combine the chopped corned beef, sauerkraut, Swiss cheese, breadcrumbs, egg, Dijon mustard, garlic powder, onion powder, paprika, salt, and pepper. Mix until well combined.
2. Form the Balls: Take small portions of the mixture and roll them into balls, about 1 inch in diameter. Place them on a baking sheet lined with parchment paper.
3. Heat the Oil: In a large skillet, heat oil over medium heat. You need enough oil to cover the bottom of the pan.
4. Fry the Balls: Once the oil is hot, carefully add the Reuben balls to the skillet. Fry for about 3-4 minutes on each side until they are golden brown and crispy.
5. Drain the Balls: Once cooked, transfer the balls onto a plate lined with paper towels to drain any excess oil.
6. Prepare the Dipping Sauce: In a small bowl, mix together the mayonnaise, ketchup, horseradish sauce, hot sauce, salt, and pepper until smooth and well combined.
7. Serve: Arrange the Reuben Balls on a serving platter and serve them warm alongside the Spicy Thousand Island Dipping Sauce.
