A staple of classic Japanese cooking, teriyaki is wonderful with not only seafood but also poultry, beef, vegetables, and tofu. Often, however, this versatile sauce can be quite sweet. My version uses fresh orange juice, which adds just a touch of natural sweetness as well as some acidity to temper the sweet mirin. Pouring some of the teriyaki sauce into the hot pan with the fish further reduces it so the sauce really coats the fish with a deep, caramel glaze that enhances the delectable moist, buttery, and tender qualities of black cod perfectly. Other good fish for this dish are Alaskan cod, true cod, sablefish, or wild salmon. Searing each side of the sticky rice cake gives a nutty flavor and crisp texture. I also like to serve these rice cakes with vegetable stir-fries in place of plain rice. If you have a rice cooker, use it to prepare the rice according to the manufacturer's directions. If not, follow the instructions in the recipe to prepare it in a saucepan.
