A canape is really what we call in England an " open sandwich." It is more honest, in a way, than the ordinary sandwich, which hides its contents and is deceptive, as we often find in it something quite different from what we expected.
A few slices of lean ham, butter, mustard, • bread.
Pound the ham in a mortar, and work into a paste with butter and a little made mustard. When quite smooth, pile on neat rounds of buttered bread.
