Use a food processor to quickly and evenly chop the fish fillets if desired.Chill the fish cake mixture in the refrigerator for 30 minutes before shaping to help it hold together better.Wet your hands with cold water to prevent the fish cake mixture from sticking to your hands while shaping the patties.Use a non-stick skillet or ensure that the skillet is well greased to prevent the fish cakes from sticking during frying.Make a smaller test patty first to adjust the seasoning and consistency of the mixture if needed.If you prefer a crispier coating, coat the fish cakes in flour before frying.If you're short on time, you can use store-bought tartar sauce or aioli instead of making the dill mayo from scratch.
