Combine everything but pork and kumquats.
Use blender if you have one, and let ingredients liquefy.
Cut pork in 1-inch cubes, and thread on 6 skewers.
Brush meat generously with sauce.
Place skewered meat in greased baking pan, and refrigerate, covered, 1/2 hour.
Put in 375Ã‚Â°F. oven, and roast, 20 minutes.
Turn skewers, and brush with remaining sauce; continue cooking until meat is tender, about 20 minutes more.
Garnish ends of skewers with preserved kumquats, crab apples or sweet pickles.
