I was in an Asian grocery recently and bought a 2-pound bag of raw peanuts. It took a bit of time to boil them but that was worth it. They tasted as good as I had remember them from my childhood living in the Mekong Delta (Vietnam).
2 lbs raw peanuts, rinsed
1 tsp salt (optional)
1) In a large pot add the peanuts.
2) Add salt (if interested) and water.
3) Cover the pot and let the water boils gently, add more water as needed during cooking, cook about 1 1/2 to 2 hours or until the nuts are soft to your liking.
