Mix the chicken with the pickle juice, egg, salt and pepper. Cover and set aside in the fridge for a few hours
Mix the crushed chips with the cornmeal and mash it up until it is all one texture.
Bring half the butter, along with the stock and milk to a simmer. Whisk in 1/2 cup of the cornmeal mixture. Turn to low and continue to simmer and stir for about a half hour.
Meanwhile, bring the oil to 350 in a heavy cast iron pot. One by one take the chicken out of the marinade and dredge it in the cornmeal mixture. Fry about 3-5 minutes per side to brown and cook through.
when the chicken is just about done, add the berbere to a bowl with the garlic powder and some salt and pepper. Take a few spoonfuls of the hot frying liquid and add them to the bowl with the spices. Stir to combine and add more oil if needed to form a thin sauce.
Remove the chicken from the oil to a cooling rack and drizzle on the spiced oil.
Add the remaining butter to the grits and stir well. If it seems to thick you can add a little milk.
Serve the grits first, then top with the chicken. Add some hot sauce, chili flakes, and scallions as desired.
