Roommate went on a shopping spree at the Asian grocery store on Xmas Eve (nothing else was open). One of the treasures he returned with was something called White-Gourd Juice. We both tried it and it's not terrible (meaning it didn't make me dry heave), it's just pretty obvious that it's not a fruit.
(In your Asian drink experiments, please remember to stay away from durian- a dining companion practically cleared the table one night at a Brookline restaurant. His durian smoothie smelled like someone mixed onions and dog poo in the blender before plunking it down on our table. How appetizing.)
