Maguro tataki is a seared tuna dish that combines the freshness of raw tuna with the smoky flavors of a quick sear. To make this dish, you will need fresh maguro tuna, soy sauce, sesame oil, garlic, ginger, green onions, and sesame seeds. Start by seasoning the maguro with salt and pepper. In a hot skillet, sear the maguro on all sides for about 30 seconds to 1 minute per side, depending on the thickness of the tuna. Remove the maguro from the skillet and let it rest for a few minutes. In the meantime, prepare the tataki sauce by mixing together soy sauce, sesame oil, minced garlic, grated ginger, and chopped green onions. Slice the maguro into thin pieces and arrange them on a plate. Drizzle the tataki sauce over the maguro and sprinkle with sesame seeds. The maguro tataki is a flavorful and elegant dish that can be served as an appetizer or as part of a main course.
