56. STURGEON SAUCE.
TAKE some of the liquor in which the sturgeon has been braized,
and having reduced it to one-third of its quantity, add half a bottle
of claret or port, a ladleful of worked Espagnole sauce, and some
essence or trimmings of mushrooms; allow the sauce to clear itself
by boiling gently on the side of the stove fire, skim it, reduce it, and
then pass it through a tammy into a bain-marie. Just before using
the sauce, mix in a pat of butter, some nutmeg, cayenne, essence of
anchovies, and lemon-juice.
