An unopened fortune cookie
A fortune cookie was a type of cookie from Earth that contained a piece of paper with a "fortune" inside. They were often served in Chinese restaurants.
Gabriel Lorca's family made fortune cookies in the 22nd century, and Lorca kept a bowl of them in his ready room on the USS Discovery. In 2256, he offered one to Michael Burnham as a symbol for the possibilities of working on his ship. When the Discovery returned from the Mirror Universe and Lorca's deception was revealed, Vice-Admiral Katrina Cornwell used a phaser to vaporize Lorca's bowl of fortune cookies in anger.(DIS: "Context Is for Kings", "The War Without, The War Within")
