Yeeeees. I have always wanted to try those colorful food cubes!! Leave more Klingon food for the rest of you in this thread to enjoy. You can have my gagh.
Never tried any Klingon dishes, but I doubt I can function in the morning without my venti raktajino from Star(trek) Bucks.
Gagh is probably not one of the things i'd like to taste. I'd like to try hasperat, rokeg blood pie and the things Worf, Korris and Konmell ate in "Heart of Glory". And for drinking i would go for Romulan Ale :-)
Those cubes where just fruit juce in gelatine I think...something you could make yourself very easily using an ice cube tray.
Romulan ale is illegal! Those cubes were rumored to be a wide variety of things. Some were said to be dyed marshmallows, others were supposed to be dyed cubed melon and pineapple pieces. Some variation of all of the above is my guess.
In-universe, it's an Andorian food called Gristhera which is said to be well liked by many different races, thus explaining why we always see it served at diplomatic functions such as "Journey to Babel".
I'd try anything once as long as there was a sickbay nearby, but I can't say any of the Klingon dishes look appealing.
