Fried murt cake was a food.

Neelix served fried murt cake for lunch aboard the USS Voyager in 2372, along with Seltin pâté, niccel strips, and deviled throk. At the time, Captain Kathryn Janeway was hallucinating and believed that Neelix had instead served cucumber sandwiches, which was slightly unusual and which she commented on. She later confirmed she was hallucinating by asking Neelix about the menu, and confirming that he had indeed served fried murt cake and not cucumber sandwiches. (VOY: "Persistence of Vision")
