The heart of the boar-like targ, a Klingon dish traditionally believed to give courage to the one who eats it, tried by Riker in A Matter of Honor.
Heart of targ is one of the best-known dishes in Klingon cooking, made from the heart of the targ, a tusked animal that Klingons both hunt and keep as pets.
It is seen in The Next Generation episode A Matter of Honor, set in 2365, when Riker tries Klingon food in Ten Forward before joining the crew of the Pagh. He remarks on the old belief that the dish brings courage to whoever eats it, and Doctor Pulaski takes one look and leaves him to it.
The dish recurs in later series. In Deep Space Nine, Klingon warriors feast on it aboard their ships, and Enterprise shows targ kept as food stock on a Klingon vessel in Sleeping Dogs, more than two centuries earlier.
