One 28-ounce can diced peeled tomatoes with their juices
1 tablespoon tomato paste dissolved in 1/2 cup water
Two 2-inch-long strips of orange zest
1 1/2 teaspoons anchovy paste
Salt and freshly ground pepper
1/4 cup mayonnaise
Cayenne pepper
3/4 pound shelled and deveined large shrimp
cut into 1-inch pieces
3/4 pound sea scallops

Instructions
Preheat the oven to 350.
In a medium saucepan, heat the olive oil until shimmering.
Add the onion, carrot and three-fourths of the garlic and cook over moderately high heat, stirring occasionally, until softened, about 3 minutes.
Add the wine and cook until evaporated, about 3 minutes.
Stir in the clam juice, the tomatoes and their juices, the diluted tomato paste, orange zest and 1/2 teaspoon of the anchovy paste; season with salt and pepper.
Simmer over moderately high heat until reduced by half, about 15 minutes.
Discard the orange zest.
Transfer half of the soup to a blender and coarsely puree.
Return the puree to the soup in the saucepan.
Meanwhile, in a small bowl, stir the mayonnaise with the remaining garlic and 1 teaspoon of anchovy paste.
Season the aioli with cayenne.
Return the soup to a gentle boil.
Add the shrimp and scallops and simmer until just cooked through, about 3 minutes.
Serve the soup in deep bowls; pass the aioli at the table.
