Balut eggs are very common to us, it is called duck embryo that is boiled and eaten in the shell. It is a common food in everyday life and anyone knows balut eggs are more calories, protein and fats. I am one of those people who eat balut egg except the fetus of duck inside. A ballot egg is from a duck contains a high protein and fat. Anyway, balut are mostly sold by street vendors. It is commonly sold as streetfood here in the Philippines. Like the photo below, every night around 7:00pm to 9:00pm the balut vendors sell her balut and chicharon baboy in our Subdivision. I took a photo during my neighbors eat balut with salt and vinegar.
Another photo below when my nephew Vince goes outside the house after he eats balut. Yes, he loves to eat balut and everytime he heard balut vendors I bought one for him. I was really amazed because he eats a fetus of duck while I do not want to eat like that.
