For a refreshing and elegant dish, try making hirame sashimi with ponzu sauce. Start by slicing the hirame fillets into thin, bite-sized pieces. Arrange the slices on a plate and garnish with thinly sliced scallions and grated daikon radish. In a small bowl, mix together soy sauce, citrus juice (such as yuzu or lemon), and a touch of mirin for the ponzu sauce. Drizzle the ponzu sauce over the hirame slices and serve immediately. The delicate flavor of the hirame pairs perfectly with the tangy and citrusy ponzu sauce. This dish is a great appetizer or light lunch option.
