Cut the fish up the back; clean, and scale it, and take out the
roe, but do not wash it. Take the bone neatly out. Rub it well
inside and out with a mixture of salt and fine Havanna sugar, in
equal quantities, and a small portion of saltpetre. Cover the fish
with a board on which weights are placed to press it down, and let
it lie thus for two days and two nights. Drain it from the salt,
wipe it dry, stretch it open, and fasten it so with pieces of
stick. Then hang it up and smoke it over a wood fire. It will be
smoked sufficiently in five or six days.
When you wish to eat it, cut off slices, soak them awhile in
lukewarm water, and broil them for breakfast.
