Cook the tongue as before, and when done fix it on the dish upon mashed
potatoes; have ready the following ragout: cut four middling-sized
cucumbers into pieces about an inch and a half in length, split each
piece in three, take out the seeds from each piece, peel them and trim
them at the corners, put them in a stewpan with an ounce of butter, half
a spoonful of powdered sugar, and two chopped eschalots; stew the
cucumbers very gently till quite tender, but not to break them, then
cut the breast of a cooked fowl into slices the size of the pieces of
cucumber and add with them; then add a quart of hot bechamel sauce (No.
7) and a little white stock, shake the stewpan over the fire, but do not
stir it with a spoon, or you would break the contents; finish with a
liaison made from the yolk of one egg, pour it round the tongue, and
serve.
