Dog Claw is a hard-shelled goose barnacle, or Percebes, living in the rock cracks of Wanshan Island. Unmistakably shaped like a dog's paw, its protein-rich meat comes in three colors -- all delicious, sweet, fine and tender. It may be scalded, steamed, cooked in porridge, or eaten raw dipped in mixture of light soy sauce and mashed garlic.
