Sometimes when she wanted something very pretty for breakfast, Margaret used this rule:
Open six eggs, putting the whites together in one large bowl, and the yolks in six cups on the kitchen table. Beat the whites till they are stiff, putting in half a teaspoonful of salt just at the last. Divide the whites, putting them into six patty-pans, or small baking-dishes. Make a little hole or nest in the middle of each, and slip one yolk carefully from the cup into the place. Sprinkle a little salt and pepper over them, and put a bit of butter on top, and put the dishes into a pan and set in the oven till the egg-whites are a little brown.
