Delicious Sour Pork Rib Soup
– **Cooking Instructions:**
1. **Pork Rib Preparation:** Rinse the ribs with water to remove any dirt. Boil water with a pinch of salt and briefly dip the ribs to remove impurities. Rinse again and set aside to drain. Marinate the ribs with 2 tbsp of seasoning powder for 30 minutes to absorb the flavors.
2. **Prepare Other Ingredients:** While the ribs are marinating, wash and cut the tomatoes into wedge-shaped pieces. Peel and cut the onion into wedges as well. Wash and finely chop the scallions or coriander.
3. **Cooking the Soup:** Heat 1 tsp of cooking oil in a pot. Add the onion and sauté until fragrant. Toss in the tomatoes and cook until they soften. Then, add the marinated ribs and stir-fry until they turn opaque, allowing them to absorb the flavors. Pour in about 500ml of water and bring it to a boil over high heat. Once boiling, reduce the heat to low.
4. Simmer the ribs for about 15 minutes until they are tender. If foam forms during cooking, skim it off for a clearer broth.
5. After 15 minutes, when the ribs are tender, add 2 tbsp of rice vinegar to the soup. Once it comes to a boil again, add 2 tbsp of fish sauce. Finally, taste and adjust the seasoning as needed, then turn off the heat.

Tasty Sour Ribs
– **Serving Suggestion:**
Ladle the soup into a bowl and sprinkle with chopped scallions or coriander. Enjoy this hearty and flavorful soup with hot rice, especially on chilly rainy days. The soup features tender ribs infused with spices. The broth is savory, with a mild sourness from the tomatoes and rice vinegar, balanced by the saltiness of the fish sauce.
