Fried Chicken Equipment
Cast iron skillet (a deep vintage "chicken frying" one if you can get it.
Deep fat thermometer (to test and maintain accurate temperature)
Oil or shortening in good supply (I use either Crisco/veggie shortening or peanut oil, but any veggie oil will do).
Lard is a luxury for frying chicken unless you have access to a cheap and good supply. Leaf lard is just to hard to get these days to use the large amounts required for deep frying.
Several key points to remember when frying chicken.
First the chicken should be clean, dry and near room temperature. If you take chicken right from the fridge it will be cold. That cold chicken when dropped into your hot/oil shortening will cause a huge drop in temperature. Low oil temp when frying is what causes "greasy" foods as the crust does not properly set up. When that happens foods absorb oil and you end up with a heavy and greasy product.
Season chicken how ever you please and there are as many variations as there grains of sand upon the beach. Hot, spicy, tangy, etc... Personally one uses simple Bell's poultry seasoning (there are others), abit of salt and pepper. Poultry seasonsing are usually blends of various herbs and spices known to favour that meat. Rosemary, thyme, sage, etc...
You can either sprinkle seasonings on the meat before dipping in flour, season the flour, or season the egg, buttermilk, batter bath.
"Wet" chicken (egg, buttermilk, batter, etc...) bath will hold the flour better than dry, but standard advice from above still applies, the chicken must be dry (as in coated with flour) before going into the oil. This helps avoid splattering as well. The flour coating must be even but not packed on. All the excess flour does is sink to the bottom of the frying pan and continue cooking until it burns. Much of what causes "dirty" oil is made up of excess flour and bits.
Keep an eye on the temp as shown on the thermometer. It should not go below "deep fry" area (350F) or above (near 400F). Never crowd the pan either. That coupled with too high heat creates burnt and other bad fried chicken. Remember Holk upbraiding Miss. Daisy for how she was frying chicken in the film "Driving Miss. Daisy". The woman dismisses Holk's advice in his presence but as he leaves telling her "it's your chicken...", she turns down the fire and moves the chicken about.
Of course old time cooks/housewives didn't need thermometers for frying chicken or anything else. But it took them along time of trial and error (usually learning from their mothers or other female or even male relatives) how to fry chicken properly. Even then some just couldn't grasp it, same as with pork chops.
