I make my own pork butt rub and it's great! But, i recently had to eliminate as much salt from my diet as I can. I have substituted "No Salt," which is potassium chloride, instead of sodium chloride when I season food on the table or in the pan. But, I am unsure how "No Salt" would work in my BBQ rub. And, I don't even know if I can buy "No Salt" by the pound, like I can regular salt. Perhaps Sea Salt, which is supposed to be healthier than regular salt, would be a good substitute? Does anyone know anything about these issue?
