Assam Pedas Fish

I have made Assam Pedas fish a few times now, though the taste is passable, the fish is not. What I mean is I'm not used to the type of fish found in this region and is fast discovering the most of them don't cook well in curries, most disintegrate into the curry so I end up with fish flavoured curry rather than curry with pieces of fish in it! However, my search for the perfect fish to curry here seems to be over as the plaice that I used seemed to hold together pretty well and tastes quite similar to the ray or pari which goes really well with the assam sauce. This time round, I also have my daun kesom or Vietnamese coriander which makes it a truly fragrant dish...Yumms!
