Barley is used in main dishes and soups and can be ground into flour for baked goods. The flavor is sweet and nutty. High in protein, niacin, folic acid, thiamin, calcium, magnesium, and phosphorous, it is a good substitute for rice and millet in recipes and rolled barley may be used in place of rolled oats. To prepare, boil 4 cups of water and add 1 cup of barley; reduce heat, cover, and cook 1 hour. Serve with dried fruit, raisins, honey, or grated orange rind.
