Give us your best guesses! How do humans perceive these alien foods and beverages?
Jumja stick = Sickly sweet, something like tamarind. Coheres together like a creamsicle but it's not really cold.
Romulan ale = Definitely hard alcohol, nothing like beer or "ale." So astringent that you can barely discern a taste at all. It's calibrated for Rommie taste buds. Mostly you just feel your mouth being set afire.
Tranya = Yummmmmm! Vaguely tropic fruity.
Kanar = Mildly sweet, very viscous compared with beverages humans are used to. Probably hard to stomach for humans. Intensely intoxicating, but for Cardies it's just a mild buzz.
