One of the many well known Filipino food delicacy that can be found here only in the Philippines is called "balut".
A balut is a fertilized duck (or chicken) egg with a nearly-developed embryo inside that is boiled and eaten in the shell. It is commonly sold as streetfood in the Philippines.
Balut is usually served warm and fresh. Some of the pubs in Philippines serves the balut with beers.
The Pinoys usually tap the tip of the Balut to make a small crack on the top and drink up the juices inside the egg shell. After that the Balut shell will be cracked open and a pinch of salt will be springled on the Balut. Then, get ready to ‘wallup’ the whole thing into your mouth. I’m sure it’d taste good with beer.
Balut are most often eaten with a pinch of salt, some prefer chili and vinegar to complement their egg. The eggs are savored for their balance of textures and flavors; the broth surrounding the embryo is sipped from the egg before the shell is peeled and the yolk and young chick inside can be eaten. All of the contents of the egg are consumed, although the whites may remain uneaten, due to its toughness depending on the age of the fertilized egg.
Balut is now being served as appetizers in restaurants; cooked adobo style, fried in omelettes or even used as filling in baked pastries.
