The cuisine of Lithuania has evolved over centuries from the Grand Duchy era to today. In the 13th-17th centuries, Lithuanian cuisine differentiated between rulers/knights, townspeople, and peasants. Rulers and knights ate large quantities in castles with bread as the most important food. Peasants largely ate grain products, dairy, and meat infrequently. In the 16th-17th centuries, new world foods like potatoes, tomatoes, and cocoa were slowly incorporated. German and Eastern influences introduced dishes like potato pudding and stuffed cabbage. Today, popular Lithuanian dishes include cepelinai, cold beet soup, potato pancakes, and stuffed cabbage.
