Mayonnaise of Fish.

Rub the yolks smooth with the oil, add sugar, salt, pepper, and mustard, and, when all are mixed, the vinegar, a little at a time. Set by, covered, while you cut—not chop—the fish into strips an inch long, and shred the lettuce. Mix these in a bowl. Whip the frothed white of egg into the dressing, and pour upon the salad. Stir up with a silver fork and put into a glass dish. Garnish with rings of the whites of boiled eggs.
