I went shopping for fermented black beans at the Super 88 in Boston, but came up with two glass jars- one titled 'Black bean in soy sauce' and the other 'Hot black bean.' No one who worked there spoke English, and I looked everywhere. The ingredients are black beans, oil, soy sauce, sesame oil. Not fermented?
I assume I can just use these as stir fry sauces, but where and how do I get the real fermented black beans? If I get to the Asian grocery store, am I looking for a bag, a jar, a can? I live in NYC.
