Wash beans. Soak beans in water overnight. Do not drain. Add ham hocks or bone, onion and celery salt. Cook beans until very soft, 2 1/2 - 3 hours. Remove hocks or bone. Take off meat. Chop. Set aside. Bruise beans with a large spoon, enough to cloud. Add meat, mustard, salt and pepper. Reheat, garnish with parsley.
