This Flaky Salmon Surprise transforms simple pantry staples into an elegant, comforting dish. The star is a rich, velvety filling made from flaked pink salmon, fresh cucumber, and a touch of tarragon, all bound together with a light roux-based cream sauce. Encased in golden, buttery puff pastry, these individual savory pies offer a delightful contrast of textures: the crisp, shattering crust against the smooth, creamy interior. The cucumber adds a refreshing crunch and subtle brightness that cuts through the richness of the salmon and sour cream. Perfect for a sophisticated weeknight dinner or a light lunch, this recipe is surprisingly easy to assemble. It brings a home-style warmth to the table while feeling special enough for guests. Serve with a simple green salad or steamed vegetables to balance the indulgent pastry.
