Preheat the oven to 375 F. Clean and Prep the Chicken. Save the trimming to render the fat out later.
Season Chicken all over with Rotisserie Seasoning. Place on a rack in a roasting pan, presentation down. Cook for 25 minutes. After 25 minutes, flip the chicken presentation side up and continue to cook 20 minutes.
After 45 minutes. Shut the oven off but leave the Chicken in there for 15–20 minutes. While you prepare the Sauce.
Combine all the Dipping Sauce ingredients into a Bowl and mix. Render the trimmed Chicken Fat over medium heat in a sauce pot. Remove the crackling and add the Bowl of Dipping Sauce ingredients. Bring to a boil, mixing often until thickened. Adjust the seasoning. Remove from the heat and let rest.
Notes
I like the sauce on the runny side for dipping. If you want it thicker, add another tablespoon of Potato Starch before mixing and bringing to a boil.If you want it thicker after it has cooked. Mix equal amounts of Potato Starch and Water and add it to the simmering sauce until desired consistency.
