Blend marinade ingredients in an electric food processor until fine then combine with seasoning ingredients.
Add mutton slices to the combined marinade. Mix well and leave aside to marinate for several hours. Thread each bamboo skewer with the marinated mutton slices.
Arrange the skewered meat over a barbecue pit and grill until lightly browned or cooked through. Baste constantly with a little oil when grilling. Serve immediately with any satay sauce.
