I remember seeing a post earlier concerning mangosteens.. I recently bought some frozen ones from the Hawaii supermarket in San Gabriel and was rather disappointed. At least 1/2 of them were rotten inside (which also leads me to another related question: how do you know which ones are good and which ones are rotten without opening them? i had this problem when i was buying fresh ones in thailand last summer); and even the good ones did not taste anything close to the real thing. they were sweet, but lacked that unique flavor that makes them so... good.
