J-Dog,
The spelling is perfect! The difference between just a normal beef sausage and Boerewors is the spice mix, you gotta get that right. Don't be affraid of using corriander, thats what gives it the unique flavour. I presume you're talking about the fresh type for BBQing and not the dried type like Biltong? Oh, and the best wors has sheep fat in it, to keep it moist while BBQing it.
