Instructions

1. Step 1: Rinse 1 cup sushi rice under cold water until water runs clear, then combine with 1 1/4 cups water in a pot. Bring to a boil, reduce to low, cover, and simmer for 15 minutes until water is absorbed. Remove from heat and let rice steam covered for 10 minutes.
2. Step 2: While rice cooks, mix 3 tbsp soy sauce, 2 tbsp mirin, 1 tbsp sake, 1 tsp grated fresh ginger, 1 minced garlic clove, and 1/4 tsp red chili flakes in a small bowl to create a spiced soy glaze.
3. Step 3: Heat 1 tbsp vegetable oil in a non-stick skillet over medium-high heat. Pat dry 6 oz fresh tuna steak and sear for 1 minute on each side until the edges are just cooked but center remains rare. Remove tuna and let rest.
4. Step 4: Cut 2 dried nori seaweed sheets into thin strips. Toast in the same skillet over low heat for 1 minute until fragrant but not burnt.
5. Step 5: In a small bowl, mix 1 tbsp rice vinegar, 1 tsp sugar, and 1 tsp sesame oil until sugar dissolves; gently fold this seasoning into the cooked rice.
6. Step 6: Slice the rested tuna into thin strips. Place the seasoned rice in a serving bowl, arrange sliced tuna on top, drizzle 2 tbsp of the spiced soy glaze over the tuna and rice.
7. Step 7: Garnish with toasted nori strips, 1 tbsp toasted sesame seeds, and 2 thinly sliced scallions for crunch and flavor balance.
