(Increase these quantities, depending on how much chicken you plan to make)
Note, when the exterior crust looks perfect, the interior may still be uncooked. Especially if you are doing a variation with other chicken pieces or really large chicken breasts. It is the curse of these huge chickens that they sell now. If you decided to go with a whole chicken, do your best to buy a 2.5-3 lb chicken as this will allow the interior to cook
If it isn't spicy enough, "salt" with Tony Chachere creole seasoning. Next time you make it, increase the amount of cayenne, and/or, add chopped whole serrano chiles or habanero chiles to the marinade.
Today, I came as close as I have gotten to figuring out the Gus's Fried Chicken recipe.
I started this blog back in March of 2013.
It is not the Saveur Magazine recipe and it is not the Nora Jones recipe (the two most common recipes that show up when one does a search on the Internet).
I switched to Canola oil for a while ("Canadian oil low acid"), ignoring my personal opinion that Canola oil gives food a fishy smell and taste. But I am back to recommending Crisco oil or peanut oil as my personal preferences. I just don't like Canola oil.
The important thing is:
Buttermilk - 1 1/4 cups buttermilk to....
Cornstarch - 1 cup corn starch to make the basic slurry
(experiment with reducing the amount of buttermilk to corn starch to make a thicker slurry)
(note: I've tried a water and corn starch slurry but wasn't pleased with the results. I haven't tried a water and egg with corn starch slurry though…the egg would add viscosity)
Update August 2017: It appears that a critical component is a 24 hour soaking in the slurry.
And then you will want to season to taste (I have specifically not given guidelines here as I want you to do your own homework; use your best judgement. Everyone's taste buds are different)
Paprika (this will help darken the chicken, giving it some color; I will usually do 1/4 tsp)
Cayenne (this will add heat; I will usually do a 1/2 tsp)
Black pepper (this will add heat; I will usually do a 1/2 tsp)
White pepper (this will add heat; I will usually do a 1/2 tsp)
Garlic powder (personally I just use a pinch because, for me, garlic powder adds an aftertaste to the chicken; but that is just a personal bias)
Salt (go easy on the salt; you can always add salt at the table)
Louisiana hot sauce (start off with 8 dashes per above buttermilk/cornstarch slurry)
MSG (most commercial chicken has some MSG in it; start off with 1/4 tsp and adjust to your preference with the next batch that you make)
