I found it at the Super 88 -- the Asian import grocery store. It's a little packet of white powder imported from Thailand . . . um . . . that sounds a lot worse than it is. . .

Seriously, most of the writing is in a non-English alphabet which I do not recognize, but bouncing around Wikipedia convinces me that it is probably Thai, and it is Telephone brand agar powder.

It's got a little logo of a person talking on a telephone. I'm sure that there is a logical explanation somewhere in the corporate history of the manufacturer.
