Kohada sushi is a traditional Japanese dish that showcases the delicate flavors of gizzard shad. To make kohada sushi, you will need the following ingredients: fresh kohada fillets, sushi rice, rice vinegar, sugar, salt, and nori seaweed. First, prepare the sushi rice by washing and cooking it according to the package instructions. While the rice is still hot, mix it with a mixture of rice vinegar, sugar, and salt. Let the rice cool to room temperature. Next, slice the kohada fillets into thin strips. Place a strip of nori seaweed on your hand and add a small amount of sushi rice. Top it with a slice of kohada and roll it into a tight cylinder. Repeat this process with the remaining ingredients. Serve the kohada sushi with soy sauce and wasabi for dipping. The combination of the vinegary rice and the rich, oily flavor of the kohada creates a perfect balance of flavors in this classic sushi dish.
