I have a recipe from America’s Test Kitchen, the key part is cooking it breast down for the first 2 hours, and putting salt pork (uncured bacon I think) on the back during cooking. This essentially infuses bacon fat into the bird, it’s outstanding.
I also have been deep frying them 20+ years. Did 3 at the last tailgate and one for Thanksgiving. I inject Tony's creole butter sauce and rub them with Tonys cajon seasoning. always turn out great. Use canola oil as wife cannot do peanuts.I have been deep frying ours for at least 20 years.
I season it the night before, inside and out. I used Kosmo’s Dirty Bird, but anything will work. I had a pre brined bird, otherwise you can brine it the day before seasoning.
peanut oil heated to 350, drop the bird in slowly, temp will drop, from here out shoot for 325 oil temp. Fry for 3.5 mins per pound. Temp the bird with an instant read thermometer. Let it rest a bit but beware the skin snatchers that will hover around it, circling like vultures!
I like that from set up to bird out of oil generally takes about an hour. And it frees up the oven for other things.
making soup from the bones today.
