Canh Khoai Mỡ (Vietnamese Purple Yam Soup)
Prep 15 min Cook 15 min Serves 4 Source

Ingredients

  • 24 oz purple yam
  • cooking oil
  • 1 tablespoon finely minced shallots
  • 5 oz ground pork
  • 1½ teaspoons salt
  • 5 cups water ((or stock such as pork broth, shrimp stock))
  • 1 teaspoon fish sauce ((to taste))
  • 2 oz peeled and deveined shrimp, chopped into small pieces
  • fresh herbs for garnish: chopped cilantro, scallion and saw-tooth leaves

Steps

  1. 1

    Peel the yam. Grate about half to create starch for a smooth broth, and roughly chop the rest into medium sized chunks for texture.

  2. 2

    In a pot, heat some cooking oil over medium heat and sauté the minced shallots until fragrant (about 2–3 minutes).

  3. 3

    Add the ground pork and sauté briefly then add the salt. Continue to stir and cook until no longer pink on the outside.

  4. 4

    Add the water to the pot and bring it to a boil. Then add all of the yam. Let the liquid come back to a simmer and skim off all the foam.

  5. 5

    Continue to simmer over medium heat until the yam is tender to your liking and the soup turns purple, about 15 minutes. Give the soup a stir every now and then to prevent sticking. Add fish sauce and adjust seasonings to taste.

  6. 6

    Stir in the chopped shrimp. Once the shrimp is cooked through (which is very quick), turn off the heat and transfer the soup to serving bowls.

  7. 7

    Sprinkle fresh herbs and serve hot.
