If you're a saucy fellow, you can top these cakes with lemon and garlic infused yogurt: 1/2 cup greek yogurt, 1 tsp lemon zest, 1 Tbsp lemon juice and 1/2 tsp finely minced garlic. They're also great on their own.
Preheat oven to 400F
Season salmon with 1/4 tsp of salt and fresh ground black pepper, and bake for 15 minutes. Allow to cool.
Using a fork, flake the cooked salmon into small pieces. Combine gently in a bowl with egg, 1/2 cup panko, chives, corn, mustard, mayo, lemon zest and juice until just incorporated.
Form patties 3/4" in thickness and 3" in diameter
Coat the formed patties with remaining panko crumbs, and refrigerate for at least an hour.
Heat 2-3 Tablespoons of canola oil over medium heat in a frying pan. Pan fry each patty for about 5 minutes per side, until golden brown.
