First mix all of your chicken ingredients together (except the chicken) into a blender. Run the blender so you have a smooth mixture.
Pat the chicken down, and rub all over with the mixture.
Pre-heat your oven to 325F, place the chicken in the oven and cook until the internal temp reaches 180 degrees Fahrenheit (approximately 2 hours).
Rotate your pan (if you can) every 30 minutes in the oven.
In the last 30 minutes, prepare your Aji sauce. Take all of your ingredients, toss them into a blender, run the blender, and voila you have tasty green sauce.
Once your chicken is done, serve with your sauce and enjoy!
