Katsuo Tataki is a traditional Japanese dish made with seared bonito. To make this dish, you will need the following ingredients: bonito fillets, soy sauce, mirin, sake, ginger, garlic, green onions, and sesame seeds. First, marinate the bonito fillets in a mixture of soy sauce, mirin, sake, ginger, and garlic for about 30 minutes. Then, heat a skillet over high heat and sear the bonito fillets for about 30 seconds on each side. Remove the fillets from the skillet and let them cool. Once cooled, slice the fillets into thin pieces and garnish with green onions and sesame seeds. Serve the Katsuo Tataki with a side of soy sauce for dipping. This dish is a perfect appetizer or side dish for any Japanese meal.
