In a medium bowl, combine the chicken pieces and dill pickle juice. Marinate for at least 30 minutes to soak in flavor.
After marinating, drain the pickles from the chicken and transfer the chicken to a new bowl. Pour in the buttermilk and let it soak for another 30 minutes.
In a separate bowl, whisk together flour, cornstarch, powdered sugar, garlic powder, onion powder, paprika, black pepper, and salt.
Heat oil in a deep pan or fryer to 350°F (175°C). You need enough oil to cover the nuggets as they fry.
Remove chicken pieces from the buttermilk bath, allowing excess liquid to drip off. Dredge each piece in the flour mixture, ensuring they are thoroughly coated.
Carefully place the coated chicken in the hot oil and fry in batches for about 4-5 minutes, or until golden brown and cooked through. Keep the temperature consistent; you may need to adjust the heat as you fry.
Once cooked, transfer the nuggets to a paper towel-lined plate to drain excess oil. Repeat with the remaining chicken.
Serve the nuggets warm with your favorite dipping sauces.
Notes
Arrange the nuggets on a platter with small bowls of dipping sauces for an inviting presentation, and garnish with fresh parsley or dill for a pop of color.
