Hirame nitsuke is a classic Japanese dish that features flounder simmered in a flavorful soy-based broth. Here are the ingredients you will need: - Fresh hirame (flounder) fillets - Soy sauce - Mirin (sweet rice wine) - Sake (Japanese rice wine) - Sugar - Ginger - Green onions To make hirame nitsuke, start by preparing the broth. In a pot, combine soy sauce, mirin, sake, sugar, and sliced ginger. Bring the mixture to a simmer and let it cook for a few minutes to allow the flavors to meld together. Next, add the flounder fillets to the pot and gently simmer them until they are cooked through and tender. Be careful not to overcook the fish, as it can become tough and dry. Once the fish is cooked, garnish the dish with sliced green onions for added freshness and color. Serve the hirame nitsuke hot with steamed rice and enjoy the rich, savory flavors of this comforting dish.
