Chicken legs are boneless (how to bone the chicken legs, see here)
Mix the pork sauce and garlic on the chicken leg and marinate for at least 4 hours.
Spread the marinated chicken legs on a larger tin foil (matte side of tin foil contacts the ingredients)
Roll up the chicken, then roll it up like tincoin with tin foil, tighten both ends (first roll the chicken, then wrap it in tin foil)
Preheat the oven 180 degrees, bake for 20 minutes, peel off the tin foil, brush the soup when marinated, continue to bake for about 10 minutes, cool and slice the plate! (The next ten minutes, you have to keep an eye on it, don't bake it out.)
