Gagh

Gagh is a Klingon delicacy consisting of unprocessed serpent worms. Although most Klingons prefer it live, it can be served stewed as well. Many Humans tend to find it unappetizing, though both William Riker and Jean-Luc Picard claimed to have developed a taste for it, and Julian Bashir occasionally enjoys it. 

In 2375, a shipment of gagh ordered by Jadzia Dax arrived on Deep Space 9. She ordered it for the celebration of General Martok's birthday, but Ezri Dax wanted to have it thrown out into space because the memories of eating gagh made her sick. "It's been a long time since I've had gagh. I look forward to it. Very fresh." - Picard There are at least 51 different types of gagh, each with its distinct taste and texture: Gagh is very similar to Antedean Vermicula
