Nougat is a family of confections made with sugar or honey, whipped egg whites, and roasted nuts such as almonds, walnuts, pistachios, hazelnuts, and macadamia nuts. Sometimes, chopped candied fruit is also added. The consistency of nougat is chewy, and it is used in a variety of candy bars and chocolates. The word nougat comes from Occitan pan nogat, which means "nut bread" in Latin.

There are different types of nougat, and the ingredients and preparation methods vary by country. For example, traditional Italian nougat contains honey, egg whites, and almonds, while French nougat is made with lavender honey, almonds, and pistachios.

The nougat that appears in many candy bars in the United States and United Kingdom differs from traditional recipes and consists of sucrose and corn syrup aerated with a whipping agent (such as egg white, hydrolyzed soya protein, or gelatine). It may also include vegetable fats and milk powder. Typically, it is combined with nuts, caramel, or chocolate.

In summary, nougat is a chewy confection made with sugar or honey, whipped egg whites, and roasted nuts. It is used in a variety of candy bars and chocolates and has different variations depending on the country.
