Raw peanuts and dried peanuts don't get it. They have to be green peanuts.
Boil all day? I fill a five gallon stockpot 2/3 full with green peanuts, fill with water about an inch or two over the peanuts, bring to boil and turn heat down to a medium-low boil, cover with a lid that is tilted to catch steam but not allow boil-over, boil two hours, add a cup of salt, boil another hour, turn off heat, when all of the peanuts have sunk to the bottom (saturated with water) they are ready. Drain and eat. Never had enough left over to do anything but put in a ziplock for the next day's pau hana.
Canned boiled peanuts are like canned corn - they'll do if you're hiding from nuclear winter in a fallout shelter, but pretty yucky compared to the real deal
When I lived in Florida, green peanut season coincided with the start of football season. Here in Hawaii they think boiled peanuts are made with dried peanuts. I'm on a quest for green Hawaiian peanuts. May have to try my hand at growing them myself. Dees locals need to see what boiled peanuts can really be!
