Actually, "pink salt" seems to be an American name for Curing Salt #1 which contains ~3% nitrite so it isn't anything like the pink Himalayan salt. In places they add a pink dye so that people don't accidentally confuse it with table salt as that could actually be dangerous. The curing salt only makes up a small proportion of the total salt used in the brine the recipe soaks the meat in.
Pink salt isn't very different to normal salt.
