What is Yin Yang fish?

Yin Yang fish is a dish which consists of an oil-fried whole fish whose head remains alive even after its body has been cooked. During preparation, the fish is scaled and gutted before its body is dipped into frying oil that its head is protected from. The fish is then covered in sauce and served on a plate.

A restaurant in Chiayi, Taiwan sparked outrage when it began serving the dish in 2007, with a city official and members of the public criticizing the cruelty of the dish. Following public outcry, the dish was subsequently removed from the menu. A video of a dish in 2009 was condemned by the People for the Ethical Treatment of Animals calling a video showcasing it "disgusting".
