Good protein source and may be grown in many areas of the country, not just the southern states.
I copied this simple recipe from a bag of raw peanuts:
Boiled Peanuts
Raw Peanuts, in shell
2 Oz. salt per pound of nuts
Cover with water and boil for 2 hours.
Do not let run dry.
Let soak for at least 1 hour. Longer for more flavor
Spices may be added at the beginning, such as peppers, Cinnamon, Nutmeg, etc.
Drain and eat immediately or refrigerate, or freeze in shell.
My advice:
Nuts may be dried, in or out of shell, if you prefer harder peanuts and slightly longer storage life.
They contain oils which will go rancid over time, so either freeze or store with oxygen absorbing packs.
