I found a new
Vietnamese supermarket that I have been shopping at for the last week or so. It's great to find a market where the oxtail is the same price as the whole beef tenderloin ($6.29/lb) - I'm guessing it is not prime tenderloin.
Amongst the Buddhist Style Chicken (just means it is an eviscerated chicken with the head and feet still attached), beef tendon and chicken hearts that followed me home, so did Pork Urturi (voi trung). Does anyone know what part of the animal is, and what is the best way to cook it?





It is a single piece of tough thin membrane, with solid, noncontinuous muscle on the outer edge. It is not intestine or stomach as there were separate packages of those. Via google I come up with the Spratly Islands (which this is not), or a place in Spain (again this is not a country, but animal protein).
Does anyone have any ideas?
