Ling is a kind of dried salt fish; it is cheaper than the ordinary sort of salted codfish. It should be washed and well soaked in plenty of tepid water for six hours before it is boiled in cold water; when taken out of the pot it should be divided into large flakes, mixed with mashed potatoes, and baked in a dish, as directed in the recipe for Baked Mashed Potatoes.
