Cooking Instructions:
Begin by preparing the dipping sauce. In a bowl, combine the mayonnaise, sour cream, creamy horseradish, ketchup, 1 teaspoon of paprika, and 1 teaspoon of cayenne pepper. Mix well until all ingredients are fully incorporated. Refrigerate the sauce for at least 30 minutes to allow the flavors to meld.
While the sauce is chilling, prepare the onion. Remove the top 1/4 inch of the onion and peel off the outer skin. Cut a small, flat spot on the non-root end and remove any damaged peels. Next, cut the onion into quarter sections, being careful to stay about 1/2 inch from the root. This will help the onion bloom when cooked.
To help the onion bloom more effectively, soak it in ice water for about an hour. Meanwhile, set up your breading station with a bowl of the flour mixture and a separate bowl with the beaten eggs. Prepare a second bowl with another layer of the flour mixture for the final coating.
After soaking, remove the onion from the water and gently shake off excess moisture. Dip the onion into the first bowl of flour mixture, confirming all sections are coated. Next, dip it into the egg mixture, allowing any excess to drip off, and finally coat it again with the second flour mixture.
In a deep skillet or frying pan, heat enough neutral oil to submerge the onion. Once the oil is hot (approximately 375°F), carefully place the breaded onion into the oil. Fry the onion until it's golden brown and crispy, about 3-5 minutes, turning it occasionally for even cooking.
Once cooked, remove the onion from the oil and place it upright in a shallow bowl. Serve immediately while hot, paired with the chilled dipping sauce.
Extra Tips:
For the best results, verify the oil is at the right temperature before frying to achieve that perfect crispy texture. If you want to experiment with flavors, consider adding garlic powder or Worcestershire sauce to the dipping sauce for an extra kick.
