Taste bud
From Memory Alpha, the free Star Trek reference.
The taste bud is an organ on the tongue that mediates the sensation of taste with objects that come in contact with them, including food and beverages.
In 2151 Hoshi Sato proposed that scanning the taste buds of Malcolm Reed won't help her to identify his favorite food. Doctor Phlox told her that medically there is no accounting for taste. (ENT: "Silent Enemy")
