Throw the onions in their skins into cold water, and peel them. Then put them into a saucepan of boiling water. Add a teaspoonful of salt, and let them boil about forty minutes, or until you can pierce them easily with a fork. Then put in a dish, and drain off all water. Sprinkle with salt and pepper to taste, and pour over a Drawn Butter Sauce, and serve hot. The large Spanish Onions will require about an hour to boil tender.
