You can find anything in NYC, right?
I'm looking for three things that I can't seem to find anywhere in the city (in ascending order of difficulty).
1. frozen soursop (guanabana) pulp. I even called Goya's headquarters to find out which supermarkets carry it, to no avail.
2. Thai dark sweet soy sauce. No luck at m2m.
3. Filmjolk. Oh man. I poured this soured milk over granola every morning when I was in Sweden fifteen years ago, and I still have the taste memory. It's sort of like buttermilk, but better.
What are some hard-to-find ingredients that you've located recently?
2. Kalustyan's has something on their site called "Soy Sauce, Flavor With Mushroom, Thailand" -- not sure if that's what you're looking for.

A purveyor of fresh Chinese Bayberries has eluded me... As for soursop, Kee's makes a sousop macaroon so there's probably a supplier in this city.
Not sure what you mean by "Thai dark sweet soy sauce" but if you're looking for kecap manis, the thick Indonesian soy sauce often used in Thai dishes, then it is available in most Chinatown grocery stores.
You could also try your neighborhood Thai restaurant, which would probably sell you a bottle of whatever you're seeking with no markup.
1. Soursop juice is relatively easy to find; pulp might be more dificult. The fruit is popular in Asia under such names as guyabano and mãng cầu. You might check Hong Kong Supermarket to see if they carry frozen pulp.
2. Asia Market, Hong Kong Supermarket or the Thai grocer in Chelsea Market should have what you're looking for. At the very least they will have Chinese dark soy or Indonesian kecap manis.
