Pressure cooker is very useful: Pressure cooker is good for making bomb, pressure dhall, goat meat, and even human:

A woman in Lu'an City, China, is believed to have killed her husband and boiled his dismembered body parts in a pressure cooker.

The husband was apparently drugged and tortured for three days in June by the woman, who withheld food and water, as well as beating him savagely, according to Anhui News.

In her defence, the woman claimed that she and her daughter had been abused by the spouse.

They dismembered his body with a saw, and she then boiled his body parts in a pressure cooker to cover her tracks, said the report.

How she disposed of the cooked flesh remains unclear.
