Devil Chicken (polla a la diablo)- I just saw this on Molto Mario. It looks great.

So, season a chicken with pepper flakes, salt, and pepper. Fry it up to brown it in a big pan. Throw in oven.
Halfway through cooking time, slap on a paste of mustard, pepper, olive oil, and pepper flakes. Bakes some more.

Prepare a chili oil by putting red chilis in oil, heating, cooling, then straining. When chicken is done, put chicken in a plate, cut up. Pour chili oil on top. Then make a pan sauce with juices, sherry, and parsley. Pour that on top too. Boom. Spice crusted chicken.
