2 lb. dried raw peanuts
1/2 to 2/3 cup salt
Soak peanuts in water to cover in a large stock pot at least 8 hours or up to 24 hours. (You may need to weigh down peanuts with a large plate or lid to ensure that they are fully submerged.) Drain and rinse.
Place peanuts and desired amount of salt in stock pot with 4 1/2 quarts of water; bring to a boil over high heat. Cover, reduce heat to medium-low, and cook six hours or until peanuts are tender, adding water as needed to keep peanuts covered, stirring occasionally.
Remove from heat; let stand 1 hour.
Cajun-boiled peanuts: Add 1/2 cup cajun seasoning to water when soaking. When boiling in water, use 1/2 cup salt and 5 to 7 tbsp liquid crab boil.
