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 over medium-high heat, reduce to low, cover, and simmer for 15 minutes until water is absorbed. Remove from heat and let sit covered for 10 minutes.
2. Step 2: In a small bowl, mix 2 tbsp rice vinegar, 1 tbsp sugar, and 1/2 tsp salt until dissolved. Gently fold this seasoning into the cooked rice with a wooden spatula, fanning the rice to cool it to room temperature.
3. Step 3: Dice 6 oz sushi-grade tuna into small cubes and combine in a bowl with 3 tbsp mayonnaise, 1 tbsp sriracha sauce, and 1 tsp soy sauce. Mix until the tuna is evenly coated with a creamy, spicy mayo.
4. Step 4: Cut 2 nori sheets into thin strips and lightly toast them in a dry pan over medium heat for 1-2 minutes until crisp and fragrant.
5. Step 5: Drizzle 1 tsp sesame oil over the seasoned rice and fluff gently.
6. Step 6: To assemble, place the sushi rice in a bowl, top evenly with the spicy tuna mayo, sprinkle with 2 tbsp chopped scallions, 1 tbsp toasted sesame seeds, and the toasted nori strips.
7. Step 7: Serve with 2 tbsp pickled ginger on the side to refresh the palate and enjoy immediately.
