Salt cod, or ling, must be laid in water twelve hours, to take out Tome of the salt. Then take it out, and lay it on a board for another twelve hours. This done, put it in water for twelve hours more. Put it into the water cold when you boil it, and let it continue for fifteen minutes after the water boils. This will be sufficient when the cod is very good. Parsnips or potatoes may be boiled in a saucepan by themselves. After they are enough, scrape the parsnips fine, and put them into a saucepan with milk; stir them till they are thick, and then put in a good piece of butter, and a little salt. The potatoes may be peel'd, wash'd, and dressed in the same manner. Put either into a plate; as also eggs boiled hard, chopt, and put into a bason with butter.
