Instructions
- Step 1: In a small bowl, whisk together 1/4 cup soy sauce, 2 tbsp rice vinegar, 1 tbsp finely grated fresh ginger, 1 tbsp sesame oil, 1 tsp honey, and 1 tbsp fresh lime juice until smooth. Stir in 2 thinly sliced green onions and set aside.
- Step 2: Place 3 tbsp black sesame seeds and 3 tbsp white sesame seeds on a plate and mix evenly. Pat dry 12 oz fresh tuna steak with paper towels. Press each side of the tuna firmly into the sesame seeds to coat evenly.
- Step 3: Heat 2 tbsp vegetable oil in a heavy skillet over medium-high heat until shimmering. Carefully place the tuna steak in the pan and sear for 30 seconds on each side until the sesame crust is toasted but the tuna remains rare inside.
- Step 4: Remove the tuna from heat and let rest for 2 minutes. Using a sharp knife, slice the tuna into 1/4-inch thick slices.
- Step 5: Arrange the tuna slices on a plate and drizzle with the prepared sesame-ginger vinaigrette. Garnish with remaining green onions and serve immediately.
