Dried black fungus, that is. Didn't know you get that at your local Asian grocer? Been searching all over town, and it was right there all this time? Now, you know. They also carry all of the chicken feet, or boneless duck feet at three times the price, you can eat. Been overlooking this gem-of-the-Orient-into-your-neighborhood-transplant? You shouldn't. Just ask your Mexican neighbors, they're shopping there. They know where to get the goods. And, now, so do you.
You don't necessarily have to brave the unknown food supplyer of mysterious regions, however, in order to get your hands on some chicken feet. These bizarre, but not as bizarre as you might think, treats are available at many, well known, super-chain grocery stores. Found in the meat and poultry department, wrapped in cellophane, and looking like human baby hands, they are easily identifiable.
If you dare to brave your local Asian grocer, the chicken feet can be located somewhere between the pig's uterus, and the beef tendon. If you come upon the goat head, you've gone too far.
Apparently, there are many ways to cook a chicken foot (not to be confused with the rock-n-roller retiree band playing a 55+ community near you). The method B has chosen to simmer them in coconut milk for 15 minutes. To wich, green curry paste and water were added. This mixture simmered two more hours, thus creating the base for a curry, which went on to be a separate dish, with onion, carrots, and black fungus.
