The common people in Tibet eat mutton, beef and meat of yak. Some of the Buddhists prefer vegetarian food.

Tibetans have rice, wheat and barley as staple foods, and usually they eat food made of barley, such as chamba. The so-called chamba is actually stir-fried barley. Different from the process of dealing with wheat among the Han people, barley is first stir-fried, and then milled into powder without being peeled. Chamba is often accompanied with yak or cow butter salted tea. Pour out half a bowl of yak butter tea, then add chamba into the tea, stir it with your fingers, crush it up and it is ready to eat. During festivals, Tibetans throw chamba into the air to pray for a good luck.

Tibetans like eating meat to fight the cold. The meat of yaks and sheep is the most favoured apart from beef. The meat of goats is disliked, while that of dogs, horses, and donkeys is taboo. In some areas, people do not eat fish for they regard fish as the incarnation of the god of water or due to the fear of its bone getting stuck in the throat. Other people do not eat chicken or even eggs. Food taboos differ from area to area. Tibetans are used to eating raw meat. In winter, they cut the meat into slices and hang them high up after mixing the slices with salt and a little bit of mustard oil. The meat will keep fresh in the coldness and gradually dry. In the next spring they can either eat the air-dried meat as it is or cook it.

Sweet tea and yogurt are the other two common drinks. Sweet tea is what you get when you add milk and sugar to boiling tea. It is very popular to propose a toast of tea when seeing somebody off. Yogurt is more popular in pastoral areas.

Tibetans do not eat vegetables very often. In recent years, the situation has changed a lot, but vegetables are still much more expensive than those in mainland China.

Staying in a Sakya monastery of over 600 monks for many weeks and visiting a Nunnery of over 100 nuns it was apparent that meat was part of their staple diet, from the Rinpoches (reincarnated Tulkus) downwards. The area was in what was the Kham Region of Eastern Tibet, now incorporated into the Quinghai Province of China. Rinpoche explained that as long as the meat was killed by others, it was acceptable, giving appropriate thanks, to eat the flesh.

Another staple was the momo, a steamed dumpling filled with yak, pork, mutton or chicken. My evening meal in the monastery was invariably momo.

There was a small amount of greens in at least one meal a day and always chili. Noodles also featured regularly, although I gathered this was more to do with the recent association with China rather than Tibetan tradition. In the hotels and private houses the meals always included greens and some tomatoes.

Tsamba and hot butter tea were part of the morning Puja, or prayer session, for the monks.
