Cuisine in the World of Avatar can be divided into four major categories, which follow the division of the four nations. Each nation's cuisine is characterized by specific ingredients, dishes, and cooking methods, though regional variation in cuisine is common, particularly in the Earth Kingdom.
Following the establishment of the United Republic of Nations, culinary methods began to diversify in ways previously unseen, largely due to the unique blending of different traditions in one area. Technology also began to advance on an unprecedented scale, which had an effect on how food was prepared, as well as the ability to create new culinary products.
Much of the culinary traditions of the Air Nomads were lost after their civilization was nearly wiped out at the beginning of the Hundred Year War. However, the most defining characteristic of their cuisine was a strict vegetarianism, and they were also known for their sweets, such as fruit pies and custard tarts. In keeping with their traditional philosophy of non-violence and not harming the environment, the Air Nomads cultivated their own food in ways that caused minimal environmental impact.

Because of the barren land on which they live, the people of the Water Tribe draw most of their food sources from the ocean. Staples of the cuisine include crab, sea prunes, squid, seaweed, and seal jerky. Meat generally plays an important role in many Water Tribe dishes.
Although the cuisine of the Northern and Southern Water Tribes are similar, there are certain differences. By Avatar Korra's lifetime, both tribes had re-established themselves on the international stage, and food began to diversify as imports from other nations were incorporated into local cuisines.
The main cooking styles of the Water Tribe are boiling and stewing, as they lack the resources to make more elaborate dishes. Additionally, as they live in a colder part of the world, it is more practical to have foods like stews that warm the body and less practical to have things like salads. Many foods are also dried and preserved, such as jerky made out of seal meat.
