🥗 Ingredients
The Sushi Rice Base
- 1.5 cups Short-grain Japanese rice (preferably Koshikari or Sasanishiki variety)
- 1.75 cups Filtered water (for cooking the rice)
- 3 tablespoons Rice vinegar (unseasoned)
- 1.5 tablespoons Granulated sugar
- 1 teaspoon Sea salt (fine grain)
- 1 piece Kombu (2-inch square, wiped with a damp cloth)
The Seafood
- 100-150 grams Fresh Uni (Sea Urchin) (Grade A or 'Sashimi Grade', chilled)
- 2 tablespoons Ikura (Salmon Roe) (optional, for a 'Kaisen' style burst of salt)
Dashi-Soy Drizzle
- 2 tablespoons Japanese Soy Sauce (high quality)
- 1 tablespoon Mirin (hon-mirin preferred)
- 1 tablespoon Dashi stock (prepared or instant)
Garnish and Aromatics
- 4 pieces Shiso leaves (fresh green perilla)
- 1 teaspoon Wasabi paste (freshly grated or high-quality tube)
- 1 handful Kizami Nori (shredded dried seaweed)
- 1/2 teaspoon Toasted white sesame seeds
- 1 stalk Green onions (finely sliced on a bias)
👨🍳 Instructions
-
1
Rinse the Japanese rice in a bowl with cold water, swirling with your hand. Drain and repeat 3-4 times until the water runs clear. Let the rice sit in a fine-mesh strainer for 15 minutes to drain completely.
-
2
Place the drained rice and 1.75 cups of filtered water in a heavy-bottomed pot or rice cooker. Add the piece of kombu on top. If using a pot, bring to a boil, then reduce to the lowest heat, cover tightly, and simmer for 15 minutes.
-
3
While the rice cooks, prepare the sushi vinegar (sushi-zu). In a small saucepan over low heat, combine the rice vinegar, sugar, and salt. Stir until dissolved, but do not let it boil. Remove from heat and let cool.
-
4
Once the rice is cooked, remove the kombu and let the rice stand, covered, for 10 minutes to steam. This ensures the grains are plump and fully hydrated.
-
5
Transfer the hot rice to a large wooden bowl (hangiri) or a wide glass dish. Pour the sushi vinegar over a spatula onto the rice. Use a slicing motion with the spatula to mix, avoiding mashing the grains, while fanning the rice with a hand fan to cool it quickly and give it a glossy finish.
-
6
Prepare the Dashi-Soy Drizzle by combining soy sauce, mirin, and dashi in a small saucepan. Bring to a simmer for 1 minute to cook off the alcohol in the mirin, then set aside to cool to room temperature.
-
7
Carefully remove the uni from its tray using small tweezers or a spoon. Uni is extremely delicate; handle it as little as possible to maintain its structure.
-
8
Divide the seasoned sushi rice into two deep bowls. The rice should be slightly above room temperature, not steaming hot, to prevent the uni from 'cooking'.
-
9
Sprinkle a generous layer of kizami nori over the rice. This provides a toasted, umami barrier between the rice and the seafood.
-
10
Place two shiso leaves in each bowl, slightly off-center. These act as a fragrant 'plate' for the wasabi and add a refreshing minty-basil note to the dish.
-
11
Carefully arrange the uni tongues in a radial pattern or a neat mound over the nori. If using ikura, spoon it into the center or to one side for a vibrant color contrast.
-
12
Add a small dollop of wasabi on the shiso leaf and garnish the bowl with sliced green onions and a sprinkle of toasted sesame seeds.
-
13
Serve immediately. Instruct guests to drizzle the dashi-soy mixture over the uni just before eating to preserve the texture of the rice.
💡 Chef's Tips
Always buy 'Grade A' uni which should look firm and bright orange or yellow; if it looks 'melted' or dull, it is past its prime. When seasoning the rice, use a cutting/folding motion rather than stirring to keep the grains distinct and fluffy. Ensure the rice has cooled to roughly body temperature before adding the uni; heat will cause the delicate fats in the uni to dissolve unpleasantly. If you cannot find fresh shiso, thin strips of cucumber can provide a similar refreshing crunch, though the flavor profile will change. Use a damp cloth to cover the seasoned rice if you aren't serving it immediately to prevent it from drying out.
🍽️ Serving Suggestions
Serve with a side of warm Miso Soup with silken tofu to cleanse the palate between bites. Pair with a chilled, dry Junmai Ginjo Sake to complement the creamy sweetness of the sea urchin. A small side of Gari (pickled ginger) helps refresh the taste buds after the rich, fatty uni. For a complete meal, serve with a light Sunomono (Japanese cucumber salad). Green tea (Sencha) serves as an excellent non-alcoholic pairing to cut through the richness.
