• Ingredients
  1. 1/4 cup mayonnaise
  2. 1 large egg, lightly beaten
  3. 2 tablespoons minced scallion greens
  4. 1 tablespoon capers, drained and coarsely chopped
  5. 2 teaspoons Dijon mustard
  6. 3 tablespoons fresh lemon juice, plus lemon wedges, for serving
  7. Freshly ground pepper
  8. 1/2 pound boneless smoked trout fillet, skin removed and trout flaked (2 cups)
  9. 1 cup panko
  10. 3 1/2 tablespoons extra-virgin olive oil
  11. Salt
  12. 4 cups mâche or watercress

Directions

1. In a large bowl, mix the mayonnaise with the lightly beaten egg, scallion greens, capers, Dijon mustard, 2 tablespoons of the lemon juice and 1/2 teaspoon of pepper. Add the smoked trout and toss to combine. Fold in 1/2 cup of the panko.
2. Spread the remaining 1/2 cup of panko on a plate. Form the trout mixture into eight 1-inch-thick cakes, add them to the plate and turn to coat with the panko.
3. In a large skillet, heat 2 tablespoons of the olive oil until shimmering. Add the cakes to the skillet and cook over moderate heat, turning once, until browned and heated through, about 6 minutes. Transfer the trout cakes to plates.
4. In a medium bowl, whisk the remaining 1 1/2 tablespoons of olive oil with the remaining 1 tablespoon of lemon juice and season with salt and pepper. Add the mâche and toss to coat. Transfer the salad to the plates and serve with lemon wedges.
