Preheat oven to 425°F.
Season the salmon with salt and pepper. Shingle or layer 4 thin slices of bacon over each piece then wrap around the filets.
Place a wire rack in a rimmed baking sheet then arrange salmon on rack. Roast until the bacon is crisp and the salmon is opaque, 16-18 minutes.
Meanwhile, in a small bowl, combine sour cream, Tabasco, Worcestershire, lemon juice, garlic, herbs, salt and pepper.
Serve bacon-wrapped salmon topped with ranch sour cream and garnished with radishes and scallions.
