Mock Terrapin Soup

Chop into small pieces two pounds of roasted or boiled beef, put into a
saucepan, pour in one breakfast cupful each of milk and wine, and add two ounces
of butter rolled in flour, two or three tablespoonfuls of made mustard, and a little
grated nutmeg. Place the saucepan on the fire, boil for about fifteen or twentyminutes,
turn into a tureen and serve.
