Beef Tongue Sandwich

Chop one-half pound of cold boiled tongue, put it into a mortar with the yolks
of two hard boiled eggs, one tablespoonful of made mustard, some salt, and a small
quantity of cayenne pepper, and pound it all to a paste. Dilute the paste with two
or three tablespoonfuls of cream. Cut some thin slices of bread, butter them, then
spread them with the mixture, and press them together in pairs. Cut the sandwiches
in halves, put them on an ornamental dish-paper or a folded napkin placed on a dish,
and serve.
