This is a typical Brazilian recipe that originated in the south of Brazil when men would cross the plains in wagons carrying goods back and forth. This dish was then cooked in a open camp fire during these long trips. It makes usage of long lasting ingredients - dried rice and beef.
The original dish uses salted dried beef, commonly found in Brazil, and requires the "de-salting"steps on this recipe. You can use unsalted dried beef or even jerky, in this case you may not need to soak and boil the meat, and may need to add some salt to taste.
