I need Pickled Snow Cabbage--but I can't even identify it explicity on the web, let alone in the store where there are so many kinds of pickled vegetables. Actually, I would like to MAKE it, but I can't even figure out exactly what Snow Cabbage is. One recipe showed something that looked like what my local Asian store calls Taiwan cabbage. A google image search shows napa cabbage, bok choy, mustard greens... and once they get preserved there's no identifying them! Can anyone tell me what "snow cabbage" is so I can salt-preserve/pickle it? Thanks!
