Katsuo Tataki is a simple and delicious Japanese dish made with bonito fish. To make this dish, you will need the following ingredients: bonito fillets, soy sauce, mirin, ginger, garlic, sesame oil, and green onions. To prepare the dish, start by marinating the bonito fillets in a mixture of soy sauce, mirin, grated ginger, and minced garlic for about 30 minutes. Meanwhile, heat a grill or a skillet over high heat. Once hot, add a drizzle of sesame oil and sear the bonito fillets for about 1 minute on each side, until they are lightly browned on the outside but still rare on the inside. Remove the fillets from the heat and let them rest for a few minutes. Then, slice the bonito into thin pieces and arrange them on a serving plate. Garnish with thinly sliced green onions and serve with a dipping sauce made from soy sauce, mirin, and a touch of sesame oil. Enjoy this flavorful and tender Katsuo Tataki!
