GERMAN CLUB SANDWICH: Thin slices of pumpernickel, rye, and white bread are used for this sandwich. Rub half a pound of smearcase until smooth, add three tablespoonfuls of thick cream and two of melted butter; season with pepper and salt. Spread some of this cheese mixture on a buttered slice of pumpernickel bread, followed by a slice of rye covered with cheese, covered with a slice of buttered white bread. Garnish with slice of pickle.
