Chicken soup
From Memory Alpha, the free Star Trek reference.
Chicken soup is a type of soup, made with chicken.
In 1969, Lieutenant Kyle offered chicken soup from a food slot to an air police staff sergeant who had accidentally been transported aboard the USS Enterprise. The staff sergeant was amazed that it tasted like real chicken soup. (TOS: "Tomorrow is Yesterday")
When Captain Kirk felt depressed about M-5 apparently making him useless in 2268, Kirk did not want Doctor McCoy bring him something, but McCoy replied he didn't bring chicken soup but a Finagle's Folly known "from here to Orion". (TOS: "The Ultimate Computer")
When confronted with a choice which had led to the death of Ahni Jetal in 2375, the Doctor mused with himself that he couldn't have done anything, as everything had been pre-determined 20 billion years ago, including particles binding together to "starships and holodecks and chicken soup".
