Kohada nigiri sushi is a classic sushi preparation that highlights the natural flavors of gizzard shad. To make this sushi, you will need sushi rice, kohada fillets, soy sauce, wasabi, and pickled ginger. Start by preparing the sushi rice according to your preferred method. Then, slice the kohada fillets into thin pieces and place them on top of small mounds of sushi rice. Serve the nigiri sushi with soy sauce, wasabi, and pickled ginger. The combination of the vinegared rice, the tender kohada, and the savory soy sauce creates a harmonious balance of flavors.
