mayonnaise, lemon juice, paprika, hot pepper sauce, Worcestershire
sauce and tomato paste.
Stir crabmeat into dressing. Lightly mix in melon and toss
ingredients gently until coated. Arrange shredded radicchio on 4
individual serving dishes. Spoon melon and crab mixture on
radicchio. Chill lightly. To serve, garnish with citrus slices and
mint sprigs, if desired.
