8 Servings
Ingredients
- 2 ½ quarts water
- 2 lbs pork bones
- 2 tsp salt
- 1 tbsp fish sauce nuoc mam
- 1 tsp vegetable oil
- 1 garlic clove finely chopped
- 2 shallots or 2 scallions, white parts only, finely chopped
- ½ lb crab meat canned, frozen, or fresh
- ¼ tsp freshly ground black pepper divided
- 2 tsp cornstarch
- 2 tbsp water
- 1 large egg
- 1 15 oz can white asparagus, undrained
- ¼ cup fresh coriander Chinese parsley, chopped
- ¼ cup scallion tops chopped
Instructions
Prepare the Pork Bone Broth:
- In a large stockpot, bring 2 ½ quarts of water to a boil. Add the pork bones and return the water to a boil. Once boiling, reduce the heat slightly and cover the pot. Allow the bones to boil for 1 hour, occasionally skimming off any foam or impurities that rise to the surface to maintain a clear broth.
Season the Broth:
- After one hour, remove and discard the pork bones. Stir in 2 tsp salt and 1 tbsp fish sauce to season the broth.
Sauté the Aromatics and Crab:
- In a separate skillet, heat 1 tsp vegetable oil over medium heat. Add the chopped garlic and shallots (or scallions) and sauté until fragrant, approximately 2 minutes. Add the crab meat and cook for an additional 5 minutes, stirring frequently. Season with ⅛ tsp black pepper, then transfer the crab mixture into the prepared broth.
Thicken the Broth:
- In a small bowl, dissolve 2 tsp cornstarch in 2 tbsp water. Slowly pour the cornstarch mixture into the broth while stirring continuously to ensure even distribution. This will slightly thicken the broth.
Incorporate the Egg:
- Crack the egg into a small bowl and beat lightly. With the broth at a gentle boil, slowly drizzle the beaten egg into the soup while stirring to create delicate egg ribbons. Continue stirring for 2 minutes to fully cook the egg.
Add Asparagus and Final Seasoning:
- Pour the entire contents of the white asparagus can (including liquid) into the broth. Sprinkle in the remaining ⅛ tsp black pepper and allow the soup to simmer for 3-4 minutes, or until the asparagus is heated through.
Garnish and Serve:
- Before serving, top the soup with chopped coriander and scallion tops for added flavor and color. Serve hot as a light main dish or a comforting appetizer.
