01 - Heat vegetable oil in a deep fryer or heavy-bottomed pot to 350°F (180°C). Line a tray with paper towels for draining.
02 - Pat the dill pickle slices thoroughly with paper towels to remove excess moisture, ensuring maximum crispiness.
03 - Combine all-purpose flour, garlic powder, paprika, cayenne pepper (if using), salt, and black pepper in a shallow bowl.
04 - In a separate bowl, whisk together the eggs and buttermilk until evenly combined.
05 - Place panko breadcrumbs or cornmeal in a third bowl to use for the final coating.
06 - Dredge each pickle slice first in the seasoned flour, then dip into the egg and buttermilk mixture, and finally coat thoroughly with the panko breadcrumbs.
07 - Carefully add the coated pickle slices in batches to the hot oil. Fry for 2 to 3 minutes, turning occasionally until golden brown and crisp.
08 - Transfer fried pickles to the paper towel-lined tray to drain excess oil. Serve immediately with ranch or preferred dipping sauce.
