Black licorice
Black licorice was a type of Earth black-colored candy, which wasn't to be confused with red licorice.

After the shuttlecraft Yosemite crashed on a desert planet in 2381, its replicator malfunctioned, and could only produce black licorice, which Ensign Beckett Mariner called "the least nutritious food that [tasted] the most like poison." Later, to her and Ensign Brad Boimler's disgust, they found that some edible fruit from a nearby tree-like plant also tasted like black licorice. ()

In 3189, Commander Jett Reno entered engineering test bay alpha with a piece of black licorice, which she chewed on during her time in the bay.

When Adira Tal informed Reno of the rule which prohibited food in the bay, Reno retorted that licorice was not a food, but a candy. She then added that licorice was practically an accessory. ()

In 3190, while imprisoned on Booker's ship, Reno cajoled Cleveland Booker into giving her black licorice which she used to repair a hidden communicator chip explaining "The glycyrrhizic acid in licorice, when it dissolves, it conducts electricity." ()
