Take the pork leg, put it in a tray, smear well with the resulting mixture, rub it in well with your hands and cover with foil. Put in the fridge to marinate for at least 6 hours.
Prior to baking, take the meat out of the fridge and leave it at room temperature for 30 min. Heat the oven to 356°F (180 °C), pour 1 cup of broth into the tray with the meat, cover with aluminum foil and put to bake.
Cook 30 min., then lower to 320°F (160 °C) and bake 1 hour. Remove the foil and bake a final 30 min. at 356°F (180 °C) until the meat gains a nice brown color.
Take the meat out and cover with foil to smother for 15 min., then cut into servings.
