Slice white bread into strips or three-cornered "sippets," and fry to a pale brown in hot butter. Drain and let them cool suddenly that they may be the more crisp. Lay upon one the thinnest imaginable slice of cool tomato, a translucent shaving of cucumber, next an anchovy picked into shreds and sprinkled with paprica and lemon-juice. Press lightly with a silver knife to keep all in place, and keep cold until served.
