A luxurious Japanese rice bowl featuring tender lobes of fresh sea urchin and glossy salmon roe draped over seasoned sushi rice. The creamy, ocean-sweet uni melts gently into short-grain rice for an elegant, delicate bite. Best assembled right before serving so each component keeps its signature texture.

Ingredients
For the seasoned sushi rice
- 2 cups (400 g) Japanese short-grain rice
- 2 1/4 cups (530 ml) cold water
- 3 tablespoons rice vinegar
- 1 tablespoon granulated sugar
- 1 teaspoon fine sea salt
For the toppings and assembly
- 8 fresh sea urchin lobes (uni), about 80 g total, kept cold
- 4 tablespoons (60 g) salmon roe (ikura)
- 2 nori sheets, cut into thin 1/4-inch strips
- 2 scallions, thinly sliced on the bias
- 1 teaspoon prepared wasabi
- 4 teaspoons light soy sauce
- 1/4 cup avocado slices (optional)
- 1 sheet toasted nori, crumbled, for garnish
Directions
- Rinse the rice in cold water 3 to 4 times, swirling until the water runs nearly clear, then drain and let the rice rest in the strainer for 10 minutes.
- Combine the rice and 2 1/4 cups water in a heavy saucepan over medium-high heat; bring to a boil, cover, reduce heat to the lowest setting, and simmer for 15 minutes without lifting the lid.
- Remove the pot from the heat and let it stand, covered, for 10 more minutes to finish steaming.
- Whisk the rice vinegar, sugar, and salt in a small bowl until fully dissolved, then fold the seasoning into the warm rice with a gentle cutting motion and let it cool to just-warm, about body temperature.
- While the rice finishes, slice the scallions, cut the nori into thin strips, and arrange the uni, salmon roe, wasabi, and soy sauce in small dishes for table-side assembly.
- Divide the seasoned rice among 4 shallow bowls, pressing it gently into an even mound.
- Drape 2 lobes of uni over each rice mound and spoon 1 tablespoon of salmon roe alongside.
- Tuck the avocado slices and nori strips around the uni, add a small dab of wasabi at the center, and scatter with crumbled toasted nori; serve immediately with soy sauce on the side so diners can season to taste.
Cook’s Notes
- Choose uni that is bright orange to pale yellow, plump and intact, with a clean briny-sweet aroma; avoid broken or weeping lobes.
- Keep the rice just above body temperature — too hot and it will collapse the delicate uni; too cold and the flavors fall flat.
- Serve soy sauce or citrus ponzu on the side rather than drizzling over the uni, so the subtle ocean flavor stays forward.
- Assemble each bowl right before eating so the nori strips stay crisp and the uni keeps its shape.
- If fresh uni is unavailable, substitute sashimi-grade tuna, yellowtail, or salmon for a similar bowl, though the signature taste will differ.
