101 "Whaler" Fish Sandwich

This homemade fish sandwich offers a sophisticated twist on the classic seaside snack. Featuring flaky flounder fillets encased in a crisp, herb-flecked cornmeal crust, this high-protein meal is far superior to any fast-food alternative. The addition of a zesty, homemade tartar sauce provides a bright lift to the savoury fried fish, while the toasted sesame buns add a delightful nuttiness to every bite.

Traditionally inspired by iconic American recipes, this version uses fresh ingredients and a double-coating technique to ensure a perfectly golden finish. It is an excellent choice for a quick weekend lunch or a nutritious midweek dinner when you want something satisfying yet easy to prepare. Serve with a crisp green salad or a handful of oven-baked chips for a complete, family-friendly feast.

How to make 101 "Whaler" Fish Sandwich

  1. In a medium-size bowl, whisk together the milk and eggs. In another medium-size bowl, mix together the flour, cornmeal, and parsley.

  2. Season the fish with the salt and pepper.

  3. Dredge the fish through the egg mixture, then coat it thoroughly with the flour mixture.

  4. In a large sauté pan, immediately heat the oil over medium-high heat. When it is hot but not smoking, add the fillets to the pan. Cook on one side until the batter is light golden brown, about 4 minutes. Carefully turn the fillets and cook for 2 to 3 minutes more. Using a slotted spatula, remove them from the pan and drain on paper towels.

  5. Meanwhile, whisk together the tartar-sauce ingredients (if using).

  6. Slice the buns and spread the tartar sauce (if using) on the insides. Place a fillet on each bottom bun, then top with the lettuce, tomato, and cheese, if desired.
