Rappstar, biltong is dried meat - strips and droe wors is sausage made with ground meat. Some like it quite wet and others really dry. Both very good but very different. My 3 1/2 year old grand daughter calls it "biltoms".
Biltong and dry wors are very popular in South Africa. Most butchers have a selection of both, mostly beef and some venison in season and there are speciality shops in shopping malls etc. that have a large variety of diferent kinds. I have even seen snake biltong but didn't try that particular treasure.
I heard of a game rancher who got tired of people always asking him for free biltong so if it was somebody he didn't like he gave them "sitbok" (sitting buck) biltong which was actually made from baboon. Could just be an urban legend.
