You crack them open and, lo and behold, they are salty on the inside of the shell. How do they do that?
Shelled peanuts get soaked in a salt water solution (brine) under pressure. The pressure pulls the brine inside the shell. The nuts are then roasted to both cook and dehydrate them. Enterprising companies add other flavors to the brine as well to give us additional peanut experiences.
