50. WHITE OYSTER SAUCE.
Put the oysters into a stewpan, and set them to boil for five minutes
on the stove fire, drain them on a sieve, leaving their liquor in a basin;
wash and beard them, taking care to cut off the tendrons as that part
when eaten is troublesome to the teeth, and put them into a bain-
marie—reserving only the fat part; then put four ounces of butter
(more or less according to the quantity of sauce) into a stewpan with
two ounces of flour, cayenne pepper, and salt; knead these well
together, and moisten with the oyster liquor, some cream, and a
piece of glaze; stir the sauce on the fire, keeping it boiling for ten
minutes; then pass it through a tammy upon the oysters. Just
before sending to table, add a little lemon juice.
