German Fried Fish Sandwich Recipe (Fischbrötchen)

0 Finely dice the boiled egg and cornichon pickles. Remove core and finely dice half an apple. In a medium-sized bowl, whisk together mayo, yogurt, pickle juice, lemon juice and honey. Add the diced egg, pickle and apple and season to taste with salt and pepper. Finely chop the parsley and stir in.
1 Whisk the egg with some milk and salt and transfer to a deep plate or shallow bowl. Pour some flour and some breadcrumbs onto two separate plates.Pat the fish dry and season from both sides with salt, pepper and paprika powder.Dust the fish in flour, then coat in the egg mixture and finally coat in the breadcrumbs.
3 Heat butter and oil in a deep, medium-sized skillet over medium-low heat and cook the fish for 4 to 5 minutes on each side. The fish is done when the internal temperature has reached 145℉ (63℃).Transfer to a clean plate covered in paper towel.
2 Half the rolls and optionally lightly toast them in the skillet or in a toaster. Add a large leaf of lettuce to the bottom of the roll, then add the fried fish. Finally generously smear on the remoulade sauce, optionally top with some raw onion slices, and close the sandwich with the second half of the roll.Serve the remaining remoulade sauce on the side and an optional refreshing cucumber salad and/or fries.
