Tuna Poke


  • 2 cups short-grain sushi rice

  • 1½ teaspoons kosher salt, plus more

  • 2 tablespoons dried hijiki (seaweed)

  • 3 tablespoons mirin, divided

  • 3 tablespoons soy sauce, divided

  • ½ teaspoon sesame seeds, plus more for serving

  • ¼ cup unseasoned rice vinegar

  • 1 tablespoon sugar

  • ¼ cucumber, sliced in half lengthwise, sliced crosswise into half-moons

  • 1 jalapeño, thinly sliced

  • 2 scallions, thinly sliced

  • ¼ cup mixed fresh citrus juice (such as lime, lemon, and grapefruit)

  • 2 tablespoons white soy sauce or soy sauce

  • 1 teaspoon toasted sesame oil

  • ¼ cup mayonnaise

  • 1 tablespoon hot chili paste (such as sambal oelek)

  • ¾ pound highest-quality fresh tuna, cut into ½-inch pieces

  • 1 avocado, chopped

  • Tobiko (for serving; optional)


  1. Rinse and drain rice in a fine-mesh sieve several times until water runs clear. Let sit 30 minutes.

  2. Combine rice and 2 cups water in a medium saucepan, season lightly with salt, and bring to a boil. Reduce heat, cover saucepan, and simmer until rice is tender, 18–22 minutes. Remove from heat and let sit 10 minutes. Fluff with a fork; keep warm.

  3. Meanwhile, soak hijiki in ½ cup cold water in a small bowl until rehydrated and softened, 30–35 minutes. Drain and mix in a clean small bowl with 1 Tbsp. mirin, 1 Tbsp. soy sauce, and ½ tsp. sesame seeds; let sit 5 minutes. Drain.

  4. Whisk vinegar, sugar, 1 ½ tsp. kosher salt, and 2 Tbsp. water in another small bowl. Toss cucumber with a pinch of salt in another bowl and squeeze to expel excess water. Add cucumber and jalapeño to brine and let sit at least 10 minutes and up to 1 hour to pickle.

  5. Soak scallions in a medium bowl of cold water until they begin to curl, about 10 minutes. Drain and squeeze dry.

  6. Combine citrus juice, white soy sauce, oil, remaining 2 Tbsp. mirin, and remaining 2 Tbsp. soy sauce in another small bowl; set ponzu aside.

  7. Whisk mayonnaise and chili paste in a final small bowl to combine; set spicy mayo aside.

  8. Toss tuna, hijiki, drained pickles, scallions, and ponzu in a large bowl; season with salt.

  9. Just before serving, toss avocado into tuna mixture. Divide rice among bowls and top with tuna mixture, a dollop of spicy mayo, more sesame seeds, and some tobiko, if using.
