I have just read Meatheads Science of Rubs. He says that almost all commercial rubs have salt in them so he suggests making your own rubs without salt for numerous reasons, which he lists in the article. I currently have quite a few large containers of rubs I don't want to waste so I will use that up first and then likely going forward make my own seasonings/rubs in bulk. Generally in the past I've only made my own seasonings per a recipe and only enough for 1 use. So what do you guys do for the most part with your smoker meats? Buy, make your own, or both?
