The mackerel is one of the most beautiful of fish, being known by its
silvery whiteness. It sometimes attains to the length of twenty
inches, but usually, when fully grown, is about fourteen or sixteen
inches long, and about two pounds in weight. To carve a baked
mackerel, first remove the head and tail by cutting downward at 1 and
2; then split them down the back, so as to serve each person a part of
each side piece. The roe should be divided in small pieces and served
with each piece of fish. Other whole fish may be carved in the same
manner. The fish is laid upon a little sauce or folded napkin, on a
hot dish, and garnished with parsley.
