Nougat is a family of confections made with sugar or honey, roasted nuts, whipped egg whites, and sometimes chopped candied fruit. The consistency of nougat is chewy, and it is used in a variety of candy bars and chocolates. Two basic kinds of nougat exist. The first, and most common, is white nougat or Persian nougat, made with beaten egg whites and honey. The second is brown nougat (nougat noir) in French, literally 'black nougat'; croccante in Italian, meaning ('crunchy'), which is made without egg whites and has a firmer, often crunchy texture.
