Prepare a dredging station: Divide the flour into 2 deep dishes and add half of the spices to each and whisk to blend. Pour the buttermilk into bowl. Line a sheet tray with parchment paper.
Pour enough oil into a large pan with at least 5” sides so that it comes to at least 3” deep. Turn on heat to medium high to heat oil. .
Heat oven to 300*
Dredge the chicken one piece at a time in the flour, then dip in the buttermilk and then coat in flour again, making sure it is well coated. Place on a parchment lined baking sheet and repeat for the remaining chicken.
Test if your oil is ready by dropping a clump of the coating into the oil (you will have clumps of flour/buttermilk accumulate in the second dish of flour). If it sizzles quickly and floats, it's ready. If there is no action, increase the heat a bit.
Starting with thighs and drumsticks, gently drop into the oil.
Cook for 2 minutes then move the pieces about, making sure not to overcrowd the pot (about 6 pieces for a 12” diameter pot). Cook for 11-13 minutes, until uniformly golden brown. Depending on the size of your chicken pieces, you may need to cook them a bit longer. I found about 13 minutes was right.
Remove cooked chicken and place on a sheet tray with a rack, skin side up, to allow the grease to drain. Place in the oven while you cook the breast pieces, using the same process. The breasts should take a bit less time, perhaps 9-12 minutes depending on their size.
Place chicken on a serving platter, sprinkle with flaky sea salt (Maldon) and serve with Honey Hot Sauce.
