Mongolian cuisine predominantly consists of dairy products, meat, and animal fats. The most common rural dish is cooked mutton. In the city, steamed dumplings filled with meat—"buuz"— are popular. The extreme continental climate of Mongolia has influenced the traditional diet. Use of vegetables and spices are limited. Due to geographic proximity and deep historic ties with China and Russia, Mongolian cuisine is also influenced by Chinese and Russian cuisine. Society of the Mongol Empire#Food in the Mongol Empire Details of the historic cuisine of the Mongolian court were recorded by Hu Sihui in the Yinshan Zhengyao, known to us from the 1456 Ming Dynasty edition manuscript, also surviving in fragments from the Yuan dynasty. Presented to Tugh Temür in 1330, at the height of Mongol power and cultural influence, the Yinshan Zhengyao is a product of the cultural exchange (notably with the Islamic heartland in Mongol Iran) that enriched the Mongol Empire. Food scholars consider the Yinshan Zhengyao evidence for the cultural influence of the Middle East on Mongol food culture, comparable to the Columbian exchange. Wang Yuanling gives an eyewitness report of a feast at Kubilai khan's court where kumiss is served with scallions and onions, horse meat, roast mutton, venison, quail, pheasant, diced chicken (tianji) and bear meat, with red wine and congee. According to Marco Polo the Mongols hunted daily in December, January and February when the court was resident at the capital, with a portion of the lions, stags, bears and wild boars sent to the court of the Khan. The Khan was said to keep trained leopards, eagles, and wolves for hunting, and very fine lions that could hunt wild boars, cattle, stags and bears. List of wild edible plants in Mongolian cuisine Little is known of the early Mongol cuisine, other than the assumption that it would be similar to the general pastoral nomadic foodways of the Steppe. Mongols supplemented the staples of the pastoral nomadic diet (mostly milk and herd) with hunting and gathering, especially as stores of dry curd and cheese grew scarce in the late winter months.
