Kohada tempura is a unique and flavorful way to enjoy gizzard shad. To make this dish, you will need kohada fillets, tempura batter mix, vegetable oil for frying, and a food processor. Start by cleaning the kohada fillets and removing any bones. Then, cut the fillets into bite-sized pieces. Prepare the tempura batter according to the instructions on the package. Dip the kohada pieces into the batter and deep fry them in hot oil until they turn golden brown and crispy. Serve the kohada tempura with a dipping sauce made from soy sauce, mirin, and grated daikon radish for a delightful combination of flavors and textures.
