LAVER: an edible seaweed found on both the Atlantic and Pacific coasts. It is a food item of importance in Asia and in some parts of Europe. In Scotland and Ireland, under the name of "Sloak" or "Slook," it is boiled and served with butter, pepper, vinegar, etc., or fried in bacon fat after boiling. It is especially good as an accompaniment for cold meats. It is best to cook it in a porcelain saucepan, as it is liable to act on metals. Laver is rich in protein, averaging from 30% to 35% (see FOOD VALUES).
