Sage is an herb with gray-green leaves that have a slightly bitter flavor and a distinctive aroma. It is widely used with lamb, poultry, pork, and veal, and is a staple seasoning for sausage. It is sold as fresh sprigs or dried leaves. Store fresh sage in the refrigerator, wrapped in paper towels and enclosed in a plastic bag. Dried sage, found with other seasonings in all supermarkets, should be stored away from light, heat, and moisture for up to 1 year. Crush dried sage in the palm of the hand to release its flavor.
