How to Make It
In a shallow bowl, coarsely mash the diced avocado with a fork. Add the heavy cream and lemon juice and mash the mixture just until combined. Stir in the chopped cilantro and season generously with salt and pepper.
With kitchen scissors, cut the crab leg shells and pull out the crabmeat. Cut the crabmeat crosswise into 1-inch pieces and shred the crab. In a small bowl, combine the coconut milk and ginger. Fold in the crab and season with salt and pepper.
Spoon the crab and avocado into 8 small glasses. Top each shooter with an avocado wedge and serve.
