yup store bought ones are in brine....sallllllllty..lol
when you boil it, you really dont have to rinse it because you are boiling it with root vegetables and cabbage which take alot of the salt away, but it is a good idea to give it a quick rinse..
if you dont rinse them b4 you smoke them, it just concentrates the salt flavor and makes it like your are eating really salty beef jerky for example...
in canada, mostly on the east coast we have beef in a bucket, cant remember the name exactly but same idea as corned beef,
fellow canadians help me out with the name..lol
