Ox-tail Soup

Ingredients

Directions

  1. Cut the oxtails at the joints into 2-inch pieces.

  2. Slice the vegetables and mince the pork.

  3. In a stewpan, heat the pork until hot, then add the onion.

  4. Fry until the onion begins to color, then add the oxtails.

  5. Fry the oxtails for 5 to 8 minutes, browning on all sides.

  6. Cut each joint to the bone to allow the juice to escape while boiling.

  7. Transfer everything to a soup kettle and add the boiling water.

  8. Simmer gently for about 4 hours.

  9. Add the other vegetables and cloves stuck into a piece of onion.

  10. Season to taste.

  12. Serve 1 joint and 2 cups of soup for each person.
