Katsuo Tataki is a traditional Japanese dish made with seared bonito fish. To make this dish, you will need the following ingredients: bonito fillets, soy sauce, mirin, sake, ginger, garlic, sesame oil, and green onions. First, marinate the bonito fillets in a mixture of soy sauce, mirin, sake, ginger, and garlic for about 30 minutes. Then, heat a skillet with sesame oil and sear the bonito fillets for about 1 minute on each side. Once seared, let the fillets rest for a few minutes before slicing them into thin pieces. Serve the Katsuo Tataki with a garnish of green onions and a side of ponzu sauce. Enjoy this flavorful and tender dish!
