Broiled Mackerel.—Cleanse and trim the fish,
splitting it lengthwise down the back to the bone;
marinade the split fish for an hour, as in the pre-ceding
recipe, then grill or broil it for six minutes on
each side and serve very hot with a pat of maître
d'hôtel butter. In old days mackerel intended for
broiling was wrapped first in southernwood, which
was held to improve its flavour. If this be true I
know not, but to this day many gourmets advise
wrapping the fish, before laying it on the grill, in
fennel.
