The boiled peanuts recipe at WhatsCookingAmerica.net requires 5 pounds of raw peanuts in the shell, one cup of salt and 5 to 6 quarts of water. Cooks can add other seasonings to taste, such as chili powder or Cajun seasoning.
Wash the peanuts in cool running water, drain and put them into a large pot. Add the salt and water. Stir to settle the peanuts, and add more water to cover them if needed. Bring to a boil, then reduce the heat and boil gently for four hours.
Keep the peanuts covered with boiling water while cooking. After four hours, taste the peanuts to check texture and saltiness. If they are not ready, continue boiling and check every 10 minutes. When they reach the desired taste and texture, drain the peanuts and let them cool. Refrigerate up to a week or store in the freezer.
