Belarus cuisine has predominantly Slavic roots. Along with a Ruthenian influence, it is also linked with Lithuanian and Polish because of the long intermingling of these three peoples; first within the Grand Duchy of Lithuania (11th-15th centuries) and later within the Polish–Lithuanian Commonwealth (16th-17th centuries). Though the Belarusian nobility, like the Polish elite, borrowed much from Italian, German, and French cuisines, this influence hardly made itself felt in the diet of the peasant majority. Still, some of the borrowed dishes spread throughout the society, such as lazanki (a mixture of flour dumplings and stewed meat, related to Italian lasagna) and, above all, various dishes made of grated potatoes, typical for German cuisine.
