The filling may be one of several mixtures, described below:Minced Buff, chicken, or pork, combined with any or all of the following: onions, shallots, garlic, and cilantro/coriander. The mixture is usually spiced with salt, pepper, and often ground cumin. Some people also add finely puréed tomatoes, though many variations are possible.Vegetarian, predominantly made from onions and cabbage, and frequently curried. Finely diced vegetables are also added, as well as various spices.Potato, somewhat similar to Indian samosas, with small dice of firm potato in a tomato based sauce.Cheese, usually a fresh cheese, this variety is common in Bhutan and Sikkim.Snickers or Mars Bar, an original sweet momo only in touristic areas of Nepal.These fillings are then enclosed in a round of the above dough, which is sealed in a circular fashion, resembling a pinwheel, though it's also not uncommon for them to be folded in half and sealed.The resulting dumplings are then cooked by steaming over a soup (either a stock based on bones or tomato-based), which is served with the dumplings, as well as chilli sauce.Momos are commonly made in Tibet, Kathmandu, Bhutan, Sikkim, Himachal Pradesh, Siliguri, Kalimpong and Darjeeling. In Siliguri fast food stalls selling momos are very common in street corners and is one of the most popular fast foods of the town. They are very popular in Kolkata in places like Momo Plaza etc. They are also popular in Delhi.

However, the most delicious momos are available at the Central market of Lajpat Nagar, Delhi.Momos made out of Buff (meat of water buffalo) are very popular in Kathmandu, Nepal. Also popular are Momos of chicken, mutton, pork, and fish which are served in different restaurants of Kathmandu.Momos are also extremely popular in Assam, especially among the young people of Guwahati. Fried Momos:Fried momos are also very popular food in Himalayan region. These are simply pan fried or deep fried momos served with hot tomato chili sauce. Momos are steamed first and then fried with cooking oil or shortening. Many people find fried momos tasty. Usually, leftover momos from the previous night are fried for next day's brunch. They are called "Kotheys" in Nepali. Momos vs Potstickers:A common question that is asked is "what is the difference between a potsticker and a momo?" An authentic momo is actually shaped in a circle and is quite spicy and juicy. A potsticker on the other hand is shaped more like a wedge and is not as spicy. However - over time many restaurants have made the difference less and less noticeable by making momos less spicy or changing the shape to be more wedge - especially outside of Nepal. These "momos" are best called "momostickers" as they are not really the authentic form of momos.
