Types of Hirame Sushi

Fluke, or Hirame, is a favorite fish in Japanese cuisine because of its light flavor and smooth texture. It can be prepared in many delicious ways, from raw sushi to cooked dishes. Here are some popular dishes made with fluke:

Hirame Nigiri

Hirame nigiri is a classic sushi made with a slice of fluke over rice. It has a clean taste and a soft bite. Chefs often add a touch of wasabi or citrus to better its flavor.

Hirame Sashimi

Hirame sashimi is raw fluke served without rice. The thin slices highlight its mild, sweet taste. It’s often paired with soy sauce, ponzu, or a bit of wasabi.

Usuzukuri (Thin-Sliced Fluke)

Usuzukuri is fluke cut into paper-thin slices. The dish looks beautiful and tastes light. It’s usually served with ponzu sauce and garnished with herbs or radish.

Engawa Sushi (Fin Edge Cut)

Engawa comes from the fin edge of the fluke. It has a richer taste and a chewy texture. Many people see it as the most prized part of the fish.

Kobujime (Kelp-Marinated Fluke)

Kobujime is fluke wrapped in kelp to enhance its flavor. The kelp adds umami and makes the fish taste deeper. This traditional method also helps preserve the fish.

Grilled or Simmered Fluke Dishes

Fluke can also be grilled or gently simmered. Cooking gives the fish a warm, tender taste. These dishes are often seasoned lightly to keep the flavor fresh.
