Blend all of the ingredients except the pork cubes in a glass bowl. Add the pork and coat well. Cover and refrigerate for at least two hours.
Add the pork cubes to skewers. Grill over hot charcoal, basting with the marinade. After about 5 minutes, flip the kebabs.
Serve as a tapa with a glass of wine, or as a main course with grilled vegetables and rice.
