- 360ml water
- 60ml rice vinegar
- 30g sugar
- 10g salt
- 150g sashimi-grade tuna, sliced
- 150g sashimi-grade salmon, sliced
- 100g sashimi-grade scallops, sliced
- 50g ikura (salmon roe)
- 50g uni (sea urchin)

Steps
Rinse sushi rice under cold water until the water runs clear, then soak it for 30 minutes. This helps remove excess starch, ensuring a better texture.
In a pot, combine rinsed rice and 360ml of water. Bring to a boil over medium heat, then reduce to low, cover, and cook for 15 minutes. This step allows for proper steaming.
While the rice is cooking, prepare the vinegared mixture by combining rice vinegar, sugar, and salt in a small saucepan over low heat. Stir until dissolved, then cool.
Once the rice is done, let it sit covered for 10 minutes. Then transfer it to a bowl and slowly mix in the cooled vinegar mixture, fanning it to cool the rice further.
In a separate bowl, combine soy sauce, mirin, and dashi stock to create the nikiri sauce.
To serve, place a generous portion of vinegared rice in a donburi bowl. Artfully arrange slices of tuna, salmon, scallops, ikura, and uni on top.
Drizzle nikiri sauce over the seafood and garnish with shiso leaves, wasabi, and grated ginger. This enhances the flavors and adds freshness.
Why this works
Kaisen-don is a showcase of fresh, high-quality ingredients that rely heavily on the technique of preparing sushi rice and selecting sashimi-grade seafood. The rice is seasoned with a balance of vinegar, sugar, and salt, which not only enhances its flavor but also complements the richness of the seafood. Each type of fish brings its unique texture and flavor, making the arrangement both visually appealing and delicious. If the fish seems too dry or has a tough texture, ensure you're sourcing sashimi-grade seafood that is fresh; proper handling and storage are critical. Additionally, if the rice is too sticky, it may have been overcooked or not rinsed properly; in such cases, adjusting the water-to-rice ratio next time or allowing the rice to cool and dry slightly before serving can help. Kaisen-don balances various flavors and textures, making it a special-occasion dish that highlights the beauty of Japanese cuisine.
Safety note. Kaisen-don uses sashimi-grade raw seafood — the dish is defined by it. Source from a fishmonger who labels their fish sashimi-grade or sushi-grade; freezing-to-spec at -20 °C for at least 7 days is the standard safety step home cooks usually outsource to that label. For high-risk diners (pregnancy, immunocompromised, very young or old), do not serve kaisen-don — fully-cooked alternatives like tekka-don made with seared tuna or kaisen-yaki-don made with grilled white fish preserve the spirit of the bowl while moving the protein into the safe range.
