No. 559 Langue de Bœuf à la St. Aulaire.
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.
