1 1/4 lb Shrimp shelled and deveined (see note), 4 cups Seafood stock
Heat a small saucepan or grill pan over medium heat. Add a drizzle of olive oil and sauté the 6 garnish shrimp until cooked through with a golden edge. Set aside.
Meanwhile, heat the olive oil in a large pot or Dutch oven. Add the chopped leeks and cook them for 10 minutes over medium-low heat, or until the leeks are tender but not browned. Add the chopped garlic and cook 1 more minute. Add the cayenne pepper & shrimp. Cook over medium to low heat for 3 minutes, stirring occasionally.
2 cups Leeks choppped
Add the brandy or cognac and cook for 1 minute, then the dry sherry or Madeira wine and cook for 3 minutes longer.
1/4 cup Brandy, 1/4 cup Dry sherry
Transfer the shrimp and leeks to the bowl of a food processor fitted with a steel blade and process until coarsely pureed. Alternatively, transfer the shrimp and leeks to a deep bowl and roughly blend with an immersion blender. Set aside.
Using the same pot or dutch oven, melt the butter. Add the flour and cook over medium-low heat for 1 minute, stirring constantly with a wooden spoon. Add the half-and-half and cook, stirring constantly with a whisk, until thickened, about 3 minutes.
Stir in the pureed shrimp, the stock, tomato paste, salt & pepper and heat gently until hot but not boiling. Season to taste. Serve immediately garnished with fresh parsley, a sprinkling of fresh ground pepper and 1 grilled shrimp.
Notes
Keep 6 of the large shrimp with tail on for garnish in last step.
