Ingredients: 1 1/4 cups sushi rice, rinsed; 1 tablespoon unseasoned rice vinegar; 1 tablespoon sugar; Kosher salt; 2 tablespoons sesame seeds, toasted; 2/3 cup mayonnaise; 2 tablespoons fresh lemon juice; 3 to 4 teaspoons Sriracha; 1 tablespoon soy sauce; 1 teaspoon sesame oil; 1 teaspoon grated peeled ginger; 3/4 pound ahi tuna (about 1 1/4 inches thick); Kosher salt and freshly ground pepper; 1 tablespoon vegetable oil; 6 sheets nori; 1 avocado, thinly sliced; 1 cucumber, cut into matchsticks; 1 carrot, cut into matchsticks; 1/2 bunch chives, cut into 3-inch pieces; Pickled ginger, for serving (optional)

Directions

Make the rice: Put the rice in a small saucepan and add 1 1/4 cups water. Bring to a boil, then cover, reduce the heat to low and cook until the water is absorbed, about 15 minutes. Remove from the heat and let stand, covered, 10 minutes. Meanwhile, whisk the vinegar, sugar and 1 teaspoon salt in a large bowl. Gently stir in the sesame seeds and cooked rice with a rubber spatula and let cool to room temperature.
Meanwhile, make the sauce: Combine the mayonnaise, lemon juice, sriracha, soy sauce, sesame oil and ginger in a medium bowl. Cover and refrigerate until ready to use.
Make the tuna: Rub the tuna with 1/2 teaspoon each salt and pepper. Heat a nonstick skillet over medium-high heat until hot. Add the vegetable oil, then add the tuna and sear until golden brown, about 2 minutes per side. Transfer to a plate and refrigerate until ready to use, or up to 1 hour.
Assemble the rolls: Toast the nori by waving it directly over a stove burner over medium heat. Cut each sheet in half with kitchen shears to make 12 rectangles. Thinly slice the tuna and season with salt. Lay a nori rectangle on a work surface with a long side facing you. Press some rice onto the left side of the sheet using moistened fingers, leaving a 1-inch border on the left. Top with 1 slice each of tuna and avocado, a spoonful of sauce, and some cucumber, carrot and chives. Starting from the bottom left corner, tightly roll into a cone shape, moistening the edge of the nori to seal. Repeat with the remaining ingredients. Serve with pickled ginger and the remaining sauce.
