Caper Sauce.
Take a cupful of the liquor in which the meat has been boiled. Put on in a saucepan; boil and skim for a moment; stir in two tablespoonfuls of butter rubbed into a heaping teaspoonful of flour. Stir over the fire five minutes, add the juice of a lemon, pepper, and two dozen pickled capers—or, if you have not these, pickled nasturtium seed. Send to table in a boat. Save the rest of the pot-liquor for soup.
