Luncheons: A Cook's Picture Book
“ Often it is served in a deep dish, which is another mistake; for the potato, when light and white, is tempting enough to serve on a flat dish where it may be seen. Potatoes that are to be served in this way should be mashed the moment they are cooked, and not set aside for a more convenient time. They may then be moistened with milk or cream and be seasoned with butter, pepper, and salt, in measure to the richness desired, and whipped until, like the whites of eggs, they become white and spongy from the air imprisoned in the cells. Mashed potato may be served in a great variety of ways. ”
