Recipe by Alice Urquhart Fewell from the Sept. 1918 issue of The American Journal of Nursing:

Separate an egg. Put the yolk in a saucer, taking care not to break it. Beat the white until stiff and season with salt and pepper. Grease an individual baking dish, and arrange the white in it making a hollow nest in the center. In this center put a small piece of butter, and then carefully slide the yolk from the saucer into the center of the white. Season with pepper, salt and butter, and bake in a hot oven until the white begins to brown and the yolk is set. Serve at once. This is an attractive looking dish, and makes a nice change when it is necessary for a patient to have eggs frequently
