Mashed Potatoes

“Having boiled or steamed the required number of potatoes, peel them as expeditiously as possible and break them up in a hot saucepan; mash and then beat them vigorously with a wooden spoon or a fork, add a generous piece of butter, dredge with salt and a little pepper, and beat them until they are light; then moisten slightly with a very little hot milk or cream, beat them for a moment more, and serve very hot.”
