 Lutefisk does not need additional water for the cooking; it is sufficient to place it in a pan, salt it, seal the lid tightly, and let it steam cook under a very low heat for 20–25 minutes.An alternative is to wrap in aluminium foil and bake at 225 °C (435 °F) for 40–50 minutes.Another option is to parboil lutefisk, wrapped in cheesecloth and gently boiled until tender.
