1/2 lb Atlantic Cod
2 T shiro miso
1 T mirin
1 T usukuchii soy sauce or tamari
2 t sugar*
1/2 t toasted sesame oil
30g fresh ginger, grated
Oven to 425 - place fish on foil, mix other ingredients together and pour over fish and tightly seal foil to make packet. Put packet in baking dish, bake 10 min. (check to make sure its actually flaked and done)
The recipe I based this on had no sugar and had the temp as 400 and time as 8-10 min - um ... wha? Flies in the face of everything I know about cooking fish and Japanese flavors. I tried following it as written (I mean, I am no professional and I was the one looking for directions ...) but when I tasted the marinade it REALLY needed sugar (and I almost accidentally left out the sesame oil ... don't do that, it really makes it) so I tossed in *2 scant sugar shells worth of sugar ... maybe 2 t? And I ALWAYS cook fish at 425, 10 min per inch thickness ... I just skipped past 8 min, went for 10 and of course it was not done! Opened the packet, tossed it back in at 425 for about 3-5 minutes and it was perfect.
May go with aka miso or 1 T shiro and 1 T aka or 2 T shiro and 1 aka since the marinade WAS a bit soupier than I would have preferred - could have used a bit more miso kick and aka vs. shiro could make the difference.
