Yin Yang fish

Yin yang fish (also called dead-and-alive fish) is a Chinese dish where a live fish is fried whole. The dish originates from Chiayi, Taiwan.

Preparation
Yin yang fish is prepared by wrapping the head of a scaled fish (usually carp) in ice cubes and then oil-frying it whole. The fish is then covered in sauce and served on a plate where its head continues to twitch even after its body has been cooked (likely due to remnant electrical impulses after death).

Controversy
In 2007, the Taiwanese restaurant owner sparked outrage when he began serving the dish in his restaurant in Chiayi, Taiwan, 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 and banned in Taiwan.

A video of a dish in 2009 was condemned by the People for the Ethical Treatment of Animals calling a video showcasing it as "disgusting".
