Mix together the egg and milk. Place the chicken in this mixture, and let sit for at least an hour.
While the breasts are sitting, mix together the flour, sugar, salt, and pepper.
Once the sitting is done, dredge in the flour. (For ourselves and our favorite customers, after the first dredging, we would put them back in the milk bath for a few seconds, and re-dredge! This is not company policy, however!)
Place the Peanut oil in a deep fat fryer, and bring up to a high heat.
Once up to 375 F., gently drop chicken into the oil, and let cook until golden brown. (This is for those of us who do not have a pressure cooker.)
Lightly butter the buns, and grill until heated through. Place two pickles on each bun, and place a hot breast on each!
