Methods/steps

To make the marinade, combine the beer, sugar, oil, soy sauce, garlic, cayenne, vinegar, and black pepper in a non-reactive bowl. Add the beef, cover, and marinate the beef in the refrigerator overnight. Remove the beef and drain, reserving the marinade.

Put the reserved marinade in a small saucepan and simmer for 15 to 20 minutes.

Thread the beef, onions, and bell pepper on skewers. Brush the onions and peppers with oil and sprinkle with some additional chile. Grill the kebabs over a medium-hot fire for about 4 minutes on each side, until the beef is done. Cut a piece of meat to check for doneness.

To serve, place the kebabs on a serving platter or individual plates. Pour the cooked marinade over the kebabs and serve.
