My family's Canh Chua recipe is perfect for anyone looking for a healthy soup that is hearty enough to be enjoyed as a meal.
In a 4 quart or medium-sized pot, heat up a tablespoon of oil over medium heat. Add minced garlic, sliced Thai chilis and lemongrass. Saute for about 10-20 seconds, just until the garlic begins to change color.
Add tamarind concentrate, fish sauce and sugar to the pot. Mix well and allow it to come to a boil.
Add 6 cups of water, tomatoes and pineapples. Turn the heat to high and bring to a boil. Lower the heat to medium-low, cover and allow it to simmer for 10 minutes.
Uncover, turn the heat back to high then add the catfish and bring back to a boil. Reduce the heat and simmer uncovered for another 10 minutes or so, until the fish is tender. Periodically, skim off any scum or impurities.
Add bean sprouts and taro stem (bac ha), then turn off the heat. The remaining residual heat will cook the taro stems and bean sprouts.
Serve with a generous topping of fried shallots and chopped paddy herb (ngo om).
