Balut is a traditional street food popular in several Southeast Asian countries, particularly in the Philippines. It consists of a fertilized duck egg that has been incubated for about 14 to 21 days, allowing the embryo to develop partially. The egg is then boiled and typically eaten warm, often with a sprinkle of salt or vinegar. The consumption of balut is often accompanied by a cultural significance, as it is considered a delicacy and is commonly sold by street vendors. It is rich in protein and is sometimes enjoyed as a snack or a source of nutrition, reflecting local culinary practices and traditions.
