How to get started making your own sausage.
http://www.theprepperdome.com/beginners-guide-sausage-making/I find the biggest block in getting started is the recommendation for a meat grinder. Yes, it makes it far easier, but you can cut your meats and fats using a knife and cutting board. It will just take longer.
Now, pre-SHTF, you can find all of the necessary ingredients and tools in local stores and groceries. Prices are even somewhat reasonable.
I would recommend that you get some recipes for making the "salt" mixture used for almost all recipes. It is NOT simple Sodium Chloride - table salt... Plan on needing to make your own "salt" mix and using intestines for wrapping and curing.
