Sausages may taste lovely, but it’s usually best not to ask what’s actually in them. Curiosity may have killed the cat, but it was a sausage-maker who disposed of the body. In nineteenth-century America, the belief that sausages were usually made out of dog meat was so widespread that they started to be called hotdogs, a word that survives to this day. Sausages are stuffed with pork and peril. They don’t usually kill you, but they can.
