48. CARDINAL SAUCE.
Put some reduced Velouté sauce into a stewpan, add some essence
of mushrooms, lobster butter, a little essence of anchovies, lemon
juice, and cayenne; work these well together, and pass the sauce
through a tammy into a bain-marie for use.
Observe: That for whatever kind of meat or fish this sauce may be
intended, the essence or liquor of the meat or fish, should be first
reduced to glaze, and then incorporated into the sauce, in order to
give it a characteristic flavour.
