Chicken Kyiv
Chicken Kiev, also known as chicken Kyiv,[a] is a dish made of chicken fillet pounded and rolled around cold butter, then coated with egg and bread crumbs, and either fried or baked. Since fillets are often referred to as suprêmes in professional cookery, the dish is also called "suprême de volaille à la Kiev". Stuffed chicken breast is generally known in Russian and Ukrainian cuisines as côtelette de volaille. Though it has disputed origins, the dish is particularly popular in the post-Soviet states, as well as in several other countries of the former Eastern Bloc, and in the English-speaking world. The history of this dish is not well documented, and various sources make claims about its origin. Since the 18th century, Russian chefs have adopted many techniques of French haute cuisine and combined them with the local culinary tradition. The adoption was furthered by the French chefs, such as Marie-Antoine Carême and Urbain Dubois, who were hired by Russian gentry. In particular, the use of high quality meat cuts, such as various cutlets, steaks, escalopes and suprêmes became widespread in the 19th century, and a number of original dishes involving such components were developed in Russia at that time.
