A fair number of people believe that pressure cookers made in the 1980s are more reliable and better constructed than the ones being sold today. Apparently, during the golden era of pressure cooker manufacturing, cookers would make perfectly cooked rice in three whistles, whereas the modern ones tend to be temperamental. This is not true. What is true is that a fair number of Indians are using the pressure cooker the wrong away, and still achieving mostly good results, so we never bother to correct our understanding.
