A fried fish sandwich with tartar sauce and crispy chips just seem to say summer—even if it's cold outside. In this recipe, the fish is coated in a tempura-like batter, fried until crisp, and then served on a toasted bun with homemade tartar sauce and a side of hand-cut potato chips. Halibut fillets are used here, but any firm, dense fish will do.

The tartar sauce is a simple mixture of mayonnaise, diced cornichons (small gherkins), onion, and capers, making the perfect cool, creamy foil for the crispy fish. The chips are paper-thin slices of potato fried only for a few seconds, resulting in crunchy, salty chips—the perfect accompaniment!

Ingredients

  • 1/2 cup mayonnaise

  • 1/4 medium onion (diced)

  • 1 teaspoon drained capers (rinsed)

  • 6 cornichons (or small gherkins) diced

  • 1 to 2 medium potatoes

  • 2 cups vegetable oil (or sunflower oil) for frying

  • Salt to taste

Make the Sandwiches

  1. Lightly toast the buns in a toaster or on a grill or pan over medium heat for a minute or so. Assemble the sandwiches by spreading a layer of tartar sauce onto one side of the buns, followed by mixed lettuce, a fish fillet, a bit more sauce, and then the bun top.

Deep-Frying Tips

There are a few important steps to follow when deep-frying to avoid oil-laden, soggy food, including the size of the pot, the type of oil, and maintaining the oil temperature. The pot should have a heavy bottom and be deep and wide enough so that the food can stay submerged in the oil. The best oil for frying is one with a high smoke point, like vegetable oil, and it needs to remain at the target temperature, which can be monitored with a deep-fry thermometer. It's also crucial to not crowd the pan as adding too much food into the oil will lower the temperature, which in turn causes the food to absorb too much oil.
