So I picked up my first pork belly, with a plan cure and smoke it following a recipe to help me through the process. I was having a little trouble tracking down the cure #1. I located a small local butcher and once I mentioned pork belly he hands me a bag and says you actually need a rub. I verified there was cure in it, he says yes and mentioned maple flavor, but this is all he wanted to help with. So my question is, what is it he gave me? What's in it so I can still go off the recipe I was trying to follow? Also, feel free to give a pork belly newbie some tips!
