Repeat with second mango, for a total of 32 slices. Cut a round from each slice with a 3-inch cutter. Lay 16 mango rounds on a greased baking sheet and sprinkle with sugar, about 1/2 tablespoon per slice. Broil until sugar melts and browns, about 6 to 7 minutes. Divide other 16 mango rounds among 4 plates, lining up 4 rounds on one side of each plate. Spread 1 tablespoon cream cheese mixture on each mango slice. Lay 1 cooked shrimp on top of each. Top each ravioli with 1 caramelized mango slice, sugar side up. Heat 2 to 3 inches oil in a 4-quart heavy pot over moderate heat until thermometer registers 375If using carrots, slice lengthwise with a mandoline into 16 flexible strips. Roll strips into coils and secure with toothpicks. Fry coils in oil until crisp, 1 to 2 minutes. Transfer to paper towels to drain. Remove fish from refrigerator. Pour flour into a large bowl. Using a fork, transfer pieces of fish to flour and toss to coat. Fry fish in oil until crisp and brown, 3 to 4 minutes. Transfer to paper towels to drain. Re-warm passion fruit-aji sauce over low heat. Stir in passion fruit juice, 1/2 tablespoon at a time, until sauce is thin enough to drizzle. Re-warm salsa marina over low heat. Place 4 fish pieces in a vertical line on each plate, each piece opposite a mango ravioli. Spoon a little salsa marina over each piece of fish. Drizzle 4 horizontal lines of passion fruit-aji sauce across each plate, one line across each row of fish and ravioli. Remove toothpicks from carrot spirals. Arrange 4 spirals in a vertical line down the center of each plate, between fish and ravioli. Sprinkle plates with sea salt and chives, and serve.
