For a smoother texture, you can pass the cod mixture through a sieve after blending. If the mixture is too wet, add a little more potato starch to help bind it. Feel free to experiment with other seasonings, such as dill, parsley, or lemon zest. For a healthier option, bake the fish cakes in a preheated oven at 375°F (190°C) for about 20-25 minutes, or until golden brown and cooked through.
