1. Start by peeling the onions and cutting them into bite-sized wedges or thick petals. Carefully separate the layers and set them aside, ready for the coating process.

2. In one bowl, whisk together the flour, paprika, garlic powder, onion powder, cayenne pepper, and salt. In another bowl, pour the buttermilk. In a third bowl, add the panko breadcrumbs.

3. Dip each onion piece into the flour mixture, then into the buttermilk, and finally into the panko breadcrumbs. Press gently to ensure the coating sticks to the onions.

4. In a deep pot or fryer, heat the vegetable oil to 350°F (175°C).

5. Carefully add the coated onion pieces to the hot oil in small batches. Fry for 2-3 minutes or until golden brown and crispy. Remove the onions with a slotted spoon and drain them on paper towels.

6. While the Bite-Sized Blooming Onions are frying, you can prepare a delectable dipping sauce to accompany them. In a small bowl, mix together the mayonnaise, ketchup, Worcestershire sauce, horseradish (if using), smoked paprika, garlic powder, and season with salt and pepper to taste.
