In the early years, offal was used as leftover ingredients, but it was the food used by the poor to satisfy their hunger. With the passage of time, they have gone through thousands of twists and turns, relying on their own unique smell, and unexpectedly "countered attack" has become the most innovative feature in the world's delicious culture. No matter in ancient forests, bustling cities, or vast grasslands, or small towns, there are countless followers of offal and delicious food. For example, in the Philippines, pig offal can not only glimpse the subconsciousness of the local aborigines to "make the best use of everything", but also fully demonstrate the human's respect for food. What's even more surprising is that some offal are even "advanced" to become top ingredients. For example, Japanese anglerfish liver, which is compared to "foie gras under the sea", has attracted many diners because of its texture and taste.
