Dissolve kosher salt in water. Place the peanuts in the water. Place a bowl on top to keep the peanuts submerged. Soak for 1 hour.
Preheat oven to 300 degrees.
Strain the peanuts. Pat dry and place in a single layer on a baking sheet. Roast at 300 degrees for 35-45 minutes. The peanuts will be slightly underdone (a little chewy) when you remove them from the oven, but they will continue to cook once you remove them. Allow to cool for 5 minutes.
Serve warm.
Notes
Now turn on the game and enjoy one of my favorite summer past times. Just try to resist throwing the shells on the floor, they don't make for easy clean up. Enjoy!
