Amritsari Machchi

While I really like the caramel-hued malt vinegar that is used in this recipe, it is often hard to find. The closest substitute in look, flavor, and acidity (about 5%) is cider vinegar. Rawas, the fish used here, is called the Indian salmon. It is very different from American salmon. For this recipe, you can use rockfish or grouper if rawas is unavailable.
