In a large bowl mix the salmon, panko breadcrumbs, mayonnaise, shallot, chives, coriander, cayenne, lemon zest and lemon juice. Season with salt and pepper. In a small bowl lightly beat an egg, then gently fold into the salmon mixture.
Form 4 equal cakes about 4” in diameter.
Heat a large sauté pan over medium-high heat, add the olive oil and heat through. Cook the salmon cakes until golden brown and the salmon becomes opaque, about 4 minutes on each side.
For the yogurt chive sauce:
Stir together the yogurt, chives, lemon zest, lemon juice, and salt.
For serving:
Serve the warm salmon cakes with the sauce and corn or arugula salad on the side.
