Savory Sandwiches

Take some cold cooked ham, or corned beef or tongue, having one-fourth of its
quantity fat; chop it up very finely, and mix with it one teaspoonful of mustard, one
saltspoonful of salt, and sufficient cold water to form a stiff paste. Then add one-half
teacupful of butter worked to a cream. Take some very thin slices of stale bread,
spread them over with the paste, put two slices together, having the paste inside, cut
into shapes or rectangular pieces, and serve.
