Tuna Poke
2 cups short-grain sushi rice
1 1/2 teaspoons kosher salt, plus more
2 tablespoons dried hijiki (seaweed) 3 tablespoons mirin (divided use) 3 tablespoons soy sauce (divided use) 1/2 teaspoon sesame seeds, plus more for serving
1/4 cup unseasoned rice vinegar 1 tablespoon sugar
1/4 English hothouse cucumber, sliced in half lengthwise, sliced crosswise into half-moons
1 jalapeño, thinly sliced
2 scallions, thinly sliced
1/4 cup mixed fresh citrus juice (such as lime, lemon and grapefruit)
2 tablespoons white soy sauce or soy sauce
1 teaspoon toasted sesame oil
1/4 cup mayonnaise
1 tablespoon hot chili paste (such as sambal oelek)
3/4 pound highest-quality fresh tuna, cut into 1/2-inch pieces
1 avocado, chopped
Tobiko (for serving; optional)
Rinse and drain rice in a fine-mesh sieve several times until water runs clear. Let sit 30 minutes.
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.
Meanwhile, soak hijiki in 1/2 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 1/2 tsp. sesame seeds; let sit 5 minutes. Drain.
Whisk vinegar, sugar, 1 1/2 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.
Soak scallions in a medium bowl of cold water until they begin to curl, about 10 minutes. Drain and squeeze dry.
Combine citrus juice, white soy sauce, oil, remaining 2 Tbsp. mirin, and remaining 2 Tbsp. soy sauce in another small bowl; set ponzu aside.
Whisk mayonnaise and chili paste in a final small bowl to combine; set spicy mayo aside.
Toss tuna, hijiki, drained pickles, scallions, and ponzu in a large bowl; season with salt.
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.
Serves 4.
