Any firm fleshed fish will work for
this dish, and you can either buy fillets or fillet the fish yourself. In this
case a rock cod (sek6 baan1, 石斑)
tail was available at the Asian market. Instead of using salted black beans
(dau6 si6, 豆豉),
I used salted olives (haam4 gaam3 laam5, 鹹橄欖), which gives the dish a different flavor. You need to chop
and soak the salted olives before using them (but don’t soak for too long or
you’ll lose the salted olive flavor).
Enjoy!
