Have also seen it spelled "cum" one place on the internet, but don't want THAT in the title of my post! The Thais I've talked to all pronounce it "Com".
I'm sure lots of you have had this . . . little bits of lime, dried shrimp, coconut, chilis, sugar, sauce, peanut, etc. all folded up in a little pandan leaf (I think) burrito.
One of the most divine creations ever. My problem: Can't find it in LA. At Kruang Tedd, they have a version they call "spoon food," but it's just not the same without the little leaf packages . . .
At Silom market in Hollywood they told me that they have carried it before, but not regularly.
Anybody have a secret source? Thanks!
