Kohada sashimi is a traditional Japanese dish that showcases the delicate flavor and texture of gizzard shad. To make this dish, you will need fresh kohada fillets, soy sauce, wasabi, and thinly sliced green onions. Start by cleaning the kohada fillets and removing any bones. Then, slice the fillets into thin pieces and arrange them on a plate. Serve the sashimi with soy sauce, wasabi, and garnish with thinly sliced green onions. The combination of the fresh, buttery texture of the kohada and the salty umami flavor of the soy sauce makes this dish a true delicacy.
