Blueberry
From Memory Alpha, the free Star Trek reference
Blueberries are an edible fruit native to Earth. They are used to make blueberry pancakes.
In 2151, Phlox suggested that T'Pol try a bite of his blueberry pancake in order to be more adventurous in her culinary choices. He described them to her as being "quite delicious." (ENT: "Unexpected")
