Wash and remove the veins from the beef heart. Then cut it into 1 1/2 inch cubes.
In a bowl, combine the ají panca paste, garlic, vinegar, oregano (rubbed between the fingertips), oil, salt, pepper, and cumin powder. Add the cubes of heart and marinate them for about three hours. After that, prepare the remaining mixture to brush over the meat.
Heat an electric or coal grill to medium heat (grill). Once marinated, string 3 or 4 heart cubes on a anticucho skewer and cook them on the grill until they brown, while brushing them with the remaining marinade. The anticuchos should be juicy inside, not raw or dry.
Serve with slices of golden potatoes, corn, and chili sauce.
