The most important crop in Tibet is barley, and dough made from barley flour—called tsampa—is the staple food of Tibet. This is either rolled into noodles or made into steamed dumplings called momos. Meat dishes are likely to be yak, goat, or mutton, often dried, or cooked into a spicy stew with potatoes. Mustard seed is cultivated in Tibet, and therefore features heavily in its cuisine. Yak yogurt, butter and cheese are frequently eaten, and well-prepared yogurt is considered something of a prestige item. Butter tea is very popular to drink.
