Yesterday I stopped at the local Asian market, on the lookout for plum vinegar. It was an ingredient in a supposedly Asian-style coleslaw dressing. Among the many sauces there, however, there was no plum vinegar. The owner actually laughed when she heard what I was looking for. "Just mix some plum sauce with vinegar!"
On the way home I stopped by the Co-op, and wouldn't you know, they carry plum vinegar. So is this a traditional ingredient, or is it something that is more appealing to the westernized version of Asian cuisine?
Regardless, it's delicious.
