Have bread made into a large, square loaf, take off the crust from one end, butter and then cut into slices. Take the white part of lettuce, wash and wipe it perfectly dry; have ready the hard-boiled eggs, remove the yolks, put them through a sieve and rub to a perfectly smooth paste with the cream. Add the lemon juice and then stir in the whipped cream; season with red pepper and add the salt. Cover slices of bread with leaves of lettuce, put on a goodly quantity of dressing and then on top of this another slice of bread. This may be served in squares tied together with ribbon, or they may be pressed and cut into long narrow pieces. Of course, they must be made only a short time before serving.
