In Russia, a gingerbread maker was first mentioned in Kazan cadastres in 1568. Gingerbread confections are called "pryaniki" (sg. "pryanik"), derived from the Russian term for 'spices'. Historically three main centers of gingerbread production have developed in the cities of Vyazma, Gorodets, and Tula. Gingerbreads from Tver, Saint Petersburg, and Moscow were also well known in the Russian Empire. A classic Russian gingerbread is made with rye flour, honey, sugar, butter, eggs and various spices; it has an embossed ornament and/or text on the front side with royal icing. A Russian gingerbread can also be shaped in various forms and stuffed with varenje and other sweet fillings.
