Klingon gagh, no doubt, is the iconic food of the modern Star Trek canon. Whether it’s on The Next Generation or Deep Space Nine, whenever a group of Klingon warriors congregate together to share a meal and sing a song, there are two things of which you can always be assured: first, that there will be loud calls, in mixed tones of anger and levity, for another barrel of blood wine; and second, that there will be the relished consumption of gagh.

According to Memory Alpha the great wiki repository of all things Star Trek canon, gagh is a Klingon delicacy made from serpent worms. Although most Klingons preferred it live, it could also be served stewed or cold.
