What is tasso made from and how is it made? What is tasso made from and how is it made?
Having myself originally written most of the Wikipedia article on Tasso (which isn't really that extensive anyways), I feel justified paraphrasing it here:

Tasso ham is a specialty of Cajun cuisine. It is not a true ham, since it is made from the front shoulder, rather than the rear leg, of a pig. The front shoulder is a fatty and well-exercised (thus very flavorful but also somewhat tough) cut of meat. To prepare Tasso, the shoulder is boned out and sliced across the grain into fairly thick (1-3"/2.5-7.5cm) sections. The pieces are dredged in a salt, sugar, and nitrite mixture, then left to cure for a very short time (as little as a few hours). A spice mixture containing Cayenne pepper, garlic, and perhaps other spices or herbs is applied, and the meat is hot-smoked until cooked through.
