The day before, place peas in a bowl, add salt pork; add water to cover to depth of 1 inch. Let stand overnight. Next day, drain peas and salt pork and put both in a large pot with 8 cups water.
Add onion, salt and pepper and bring to a boil. Simmer 2 hours or until peas are tender. If necessary, add more water as peas cook to keep from burning. When ready to serve, stir in lemon rind.
A ham bone may be cooked with peas in place of the salt pork.Servings: 6 to 8
