Soak chicken in pickle juice and place in refrigerator for at least 2 hours.
Combine all dry ingredients in a large container and set aside.
Place peanut or vegetable oil in large skillet and heat to 350 degrees.
Drain chicken and coat each piece with dry batter.
Fry for approximately 4-6 minutes until golden brown and cooked thoroughly. Place cooked nuggets on a plate lined with paper towels to absorb excess oil.

Notes
To get those extra crunch pieces of goodness that are found on some of the nuggets, take a little bit of milk and splatter it into the dry mix before breading your nuggets. [Serious Eats]
If you don't have a thermometer and want to check if you have your oil at the right temperature of 350 degrees, you can test it by placing a couple of popcorn kernels in your hot oil. The popcorn will pop right around that temperature. [Cooking Comically]
