You can mix up the batter a few hours before you plan to cook these. I serve them with grits, but Test Kitchens Professional Angela Sellers says cooked white rice and hot sauce are a must for her family.
Drain salmon; remove skin and bones, and flake. Place salmon in a medium bowl. Stir in egg and next 4 ingredients until blended. (Batter will be wet.)
Drop salmon mixture by tablespoonfuls into hot oil in a large skillet over medium-high heat, and slightly flatten with a fork. Fry, in batches, 2 to 3 minutes on each side or until browned. Drain on paper towels. Keep warm on a wire rack in a jelly-roll pan in a 200° oven. Serve with Lemon-Caper Cream.
