Boortsog refer to one of Mongolia's famous pastries. They are deep-fried butter cookies, simply made from white flour, butter, sugar and salt mixed with water and oil for deep-frying. In Mongolia mutton fat is traditionally used for deep frying, but nowadays also increasingly vegetable oil. Boortsog are eaten as sweets or as a snack. Butter, honey or cheese can be used as topping for Boortsog, depending on how much sugar is used in cooking. Very often they are taken with tea by dipping them into the tea before eating. Industrial-made Boortsog can be purchased in most shops in Mongolia.
