 
      
    
2 large live Dungeness crabs, each about 1 1/4 - 1 1/2 pounds 
  10-12 fresh red chiles, stemmed, seeded and chopped or 6 dried Asian chiles 
  (3 inches long), stemmed, seeded, chopped and soaked in warm water to cover 
  for 10 minutes, drained 
  2 tablespoons minced garlic, or to taste 
  2 tablespoons minced shallots 
  1 tablespoon finely grated gingerroot 
  2 tablespoons vegetable oil, plus additional 
  For the sauce:
  1/2 cup ketchup 
  1 1/2 cups water 
  1 tablespoon Asian fish sauce, such as Nam Pla 
  1/3 cup Thai sweet chile sauce 
  2 tablespoons fresh lime juice 
  1 tablespoon cornstarch combined with 2 tablespoons water 
  2 large eggs, lightly beaten 
  3 tablespoons sliced scallion for garnish 
  Slices of white bread as an accompaniment, if desired 
In a casserole or large pot of boiling salted water, add the crabs and cook them for about 1 minute, or until no longer moving. Drain and set aside until cool enough to handle. To clean the crabs pull off top shells; pull and twist off each apron; remove gills. With sharp knife cut crabs into quarters, rinse and drain. In mortar and pestle or small food processor pound or process chiles, garlic, shallots and ginger with a little oil if necessary.
Combine all sauce ingredients. Heat a wok over moderately high heat. Add 2 tablespoons 
  oil and heat until hot. Add chili and garlic paste and stir-fry 1 minute. Add 
  crabs and stir-fry 2 to 3 minutes or until shells turn red. Add sauce ingredients, 
  bring to boil and simmer, covered, 5 to 7 minutes. Transfer crabs to serving 
  dish. 
  Bring sauce in wok to a boil. Stir cornstarch mixture and add to wok. Simmer 
  until thickened. Gradually add eggs in a stream, whisking, and cook for 1 minute. 
  Pour sauce over crabs and garnish with scallion. 
  Yield: 4 to 6 servings.
