How to Make It
Remove the meat from the lobster knuckles and claws. Twist the tails off the bodies. Split the tails lengthwise and remove the tail meat. Pull out and discard the black intestinal vein. Cut all the lobster into bite-size chunks.
In a mortar, pound the ginger with the sugar, garlic and chile to make a paste. Alternatively, chop the ingredients in a mini-processor. Stir in the lime juice, fish sauce and sesame oil.
In a bowl, toss the mango, cucumber, basil, mint and cilantro. Add the dressing and toss well. Arrange the lobster on top and sprinkle with the peanuts. Serve at room temperature or slightly chilled.
