2 key things needed for kfc style chicken and that is
1 msg
2 a brolier (the chicken has to be cooked at a consistent temp throughout) ideally 180
these special pressurised pans are usually computerised to maintain temperature
you can try to deep fry yourself but you must use a thermometer to maintain correct temperature
other ingredients salt, pepper thyme, oregano, marjoram, paprika and a touch of cumin.
all equal parts excluding salt and pepper which is just a pinch.
mix all these dry spices together, coat the chicken in an egg wash and flour then roll around in the mix.
this recipe works really well but you will notice the difference without the msg.
