1 1/2 pounds Sablefish (4 x 6-oz portions)
1/4 cup mirin
1/4 cup sake
4 tbsp white miso paste
3 tbsp sugar
4 tbsp sesame oil
To prepare marinade: Bring the mirin and sake to boil in over high heat. Boil for 30 seconds to evaporate the alcohol. Turn heat to low, add miso paste and sugar and whisk until completely dissolved. Remove from heat and cool to room temp. Place fish in ziploc and pour cooled marinade over. Leave in refrigerator for up to two to three days.
To cook fish: Preheat oven to 425. Pour a sesame oil in oven-proof skillet on stove on high heat. Place fish skin side up and cook until flesh side of fish is browned (approx 3-5 min). Flip fish onto skin side and place skillet in hot oven to bake until opaque and flakes easily (approx 8-10 min). Enjoy!
*For maximum flavor, marinate the fish two to three days before cooking.
