Ingredients

  • 200 g sashimi-grade sea bream (tai) loin
  • 1 tbsp sea salt
  • 100 g kombu (kelp)
  • 2 tbsp sake

Steps

  1. Sprinkle sea salt evenly over the surface of the sea bream and let it sit for 10 minutes to draw out moisture.

  2. After 10 minutes, wipe the fish dry with a paper towel to remove excess moisture.

  3. Lay the cleaned fish between two pieces of sake-dampened kombu, ensuring it is fully covered.

  4. Refrigerate the wrapped fish for 1 to 2 hours; this allows the kombu to dehydrate the fish slightly while infusing it with umami.

  5. After refrigeration, unwrap the fish and slice it thinly against the grain to serve as sashimi.

Why this works

The technique of using kombu to cure sea bream, or tai, capitalizes on two culinary principles: dehydration and umami transfer. The initial salting draws moisture from the fish, which helps the kombu adhere better and enhances flavors. As the fish marinates with the kombu, the kelp infuses its rich umami flavor into the flesh while simultaneously dehydrating it, improving the texture. This method creates a harmonious balance, making each bite tender and flavorful. If the fish seems too salty after curing, you can rinse it briefly under cold water before slicing to mitigate the saltiness. Additionally, if the slices break while cutting, ensure your knife is sharp and use a gentle, smooth motion to preserve the integrity of the delicate fish.

Safety note — raw fish. Kobujime is served raw, so treat it like sashimi: use fish sold as sashimi or sushi grade for raw eating, keep it cold from shop to plate, and eat it the same day. Fish for raw eating is normally frozen to a defined low temperature for a set time to control parasites — buy fish that meets your local raw-consumption standard, or freeze it appropriately yourself before curing. As with any raw-fish dish, serve a cooked alternative to anyone usually advised to avoid raw seafood.
