Balut (egg)

A balut (spelled standardized as balot) is a developing bird embryo (usually a duck or chicken) that is boiled and eaten from the shell. It originates and is commonly sold as street-food in the Philippines. They are common food in countries in Southeast Asia, such as Laos (khai look ໄຂ່ລູກ in Lao), Cambodia (pong tia koun ពងទាកូន in Cambodian),Thailand (Khai Khao ไข่ข้าว in Thai) and Vietnam (trứng vịt lộn or hột vịt lộn in Vietnamese). They are often served with beer. The Tagalog and Malay word balut means "wrapped".

The length of incubation before the egg is cooked is a matter of local preference, but generally ranges between 14 and 21 days.

The eating of balut is controversial due to religious, animal welfare and human health concerns.

Balut is a fertilized bird egg (usually a duck) that is incubated for 14 to 21 days, boiled or steamed, and the contents eaten direct from the shell. In balut that has been incubated for longer periods, the embryo is well developed and the features of a baby duck are recognisable. The partially-developed embryo bones are soft enough to chew and swallow as a whole. The mallard duck (Anas platyrhynchus), also known as the "Pateros duck", is considered to be the most important breed for egg production to make balut.

In the Philippines and other localities where balut is a traditional food, it is a common street-food and is also sold in stores and malls. It is a substantially higher source of protein and calcium compared to a regular unfertilized egg, and it is relatively cheaper. The Philippines were influenced by the Chinese around 1885, and since then, balut has been included as a traditional part of the culture. Wherever Filipinos migrated around the country for work, a large market of balut would develop. Controversies arose as knowledge of the food spread around the South East Asian countries and then globally. People questioned the ethics of eating the food.
