Put cooked crabs back into Wok. Cover, turn heat to low, and cook until sauce comes to a boil. Stir in cornstaarch and water. Stir and cook until sauce is thickened. Put on a serving plate.

NOTE: For a less pungent hot dish, use 1 T salted black beans and 1 dried chili pepper.
When you buy soft shell crabs, be sure they are still alive. Usually they look quite dead, weak and limp. Touch their legs, eyes, or mouth. Even if they respond only slightly and slowly, they are still alive. Refrigerate them as soon as you get home.
Cleaning them is quite simple. Clip off the eyes and mouth. Lift the top shell and remove the soft feather-like gills and discard them. Turn the crab bottom up. Tear off and discard the cartlidge. (the shape of the female''s is half-oval, the male''s is a narrow triangle).
