It's also called smoked ham. I make it every year, and it can be stored in basement about 3-5 years, and after that the meat becomes very hard to cut and eat but cant go bad never if you make it propetly. We make her the bacon same way.
This is how its made in home version, also this is thte best way. If you want I will tell you step by step way how to make it, and it's very cheap to make it, all you need is meat, beacon and salt and a little work.
