Baked Miso marinated Chilean Sea bass チリアンシーバスの味噌焼き

Chilean sea bass is a wonderful fish to eat. This is one of those rare fish you can not over cook even if you tried. The name was totally made up for marketing purposes and it is more appropriately called "Patagonian tooth fish", (you can see why they changed the name). In the past, this fish was reasonably priced, readily available and served in many restaurants but it has been over fished. In addition, many were caught illegally or "poached". This fish is on the list of "un-sustainable" fish along with tuna. I found this in our near-by gourmet market. The fish monger assured me that this particular fish was legally caught. Since we have not seen or eaten this fish for a long time I decided to try it.  I was expendissimo!

This fish can be cooked simply seasoned with salt and pepper but I marinated it in a sweet miso marinade before baking.

I got just over 1lb of Chilean sea bass for two servings. Since I did not have much Saikyo miso 西京味噌 left, I used white miso with mirin and sugar. Again, the exact proportion is a bit iffy and I have to guesstimate; white miso (3 tbs), sugar (1tbs), yuzu juice (from the bottle, 1 tsp) and mirin (2 tbs or until right consistency is reached). I marinated the fish in a Ziploc bag in the refrigerator for several hours. I removed the miso marinade by rubbing the surface with my hand so that a small amount of the marinade remains on the surface. I baked it in a 350F convection oven for 30 minutes on a metal rack set on the top of the deep baking pan so that hot air could circulate underneath the fish.

The fish is very nice--oily with a soft flaky texture and a nice sweet miso flavor. Among the  many other fish which can be over cooked so easily ending up dry, this is an exceptionally good fish. I served it with asparagus tips blanched and dressed with sesame sauce (sesame paste, sugar and soy sauce).
