I've bought two bottles of black vinegar in the past two weeks, trying to find a flavor similar to what they use at Din Tai Fung (dumpling house in Arcadia, CA) but neither one is right. One is too vinegar-y, the other is "sweetened" black vinegar and it's of course too sweet.
I've mixed the two and that is slightly better.
I confess I bought the cheapest brands. Should I just buy whatever is expensive? Or is there a particular brand(s) or words I should look for on the bottle?
I want something versatile that I can use as dip for dumplings, as well as in recipes where it would be cooked.
