Young cod that is split down the back and that has had the backbone removed with the exception of a small portion near the tail is known as scrod. Such fish is nearly always broiled, it may be served plain, but it is much more attractive when potatoes are combined with it in the form of an artistic border.
To prepare this dish, broil the scrod according to the directions given here, then place it on a hot platter and spread butter over it. Boil the desired number of potatoes until they are tender, and then force them through a ricer or mash them until they are perfectly fine. Season with salt, pepper, and butter, and add sufficient milk to make a paste that is a trifle stiffer than for mashed potatoes. If desired, raw eggs may also be beaten into the potatoes to serve as a part of the moisture. Fill a pastry bag with the potatoes thus prepared and press them through a rosette tube in any desired design on the platter around the fish. Bake in a hot oven until the potatoes are thoroughly heated and are browned slightly on the top.
