Canh Chua, Vietnamese Sweet and Sour Soup
Canh chua is the Vietnamese sour soup, usually built on tamarind and a good deal of sugar and fish sauce. The tamarind stays, the sugar becomes a blended date, and tamari plus a lot of lime carry the savory and sour notes. Add the sprouts and herbs off the heat so they keep their snap.
Ingredients
- 2 tbsp Tamarind paste
- 2 Medjool dates, pitted
- 3 Fresh tomatoes, cut into wedges
- 8 Okras, cut on the bias
- 8 oz Firm tofu, cubed
- 1 1/2 cups Cabbage sprouts / microgreens, bean sprouts
- 2 Thai bird chiles, sliced
- 3 cloves Garlic, minced
- 1 tbsp Low-sodium tamari
- 1 Lime, juiced
- 1/4 cup Cilantro, chopped
- 2 Scallions, sliced
Method
- Bring 6 cups (1.4 L) water to a simmer. Whisk in the tamarind paste until it dissolves. This sour broth is the whole identity of the soup, so taste it: it should make you wince a little.
- Blend the dates with a ladle of the hot broth and stir it back in. Canh chua is sour first and sweet second, and here the date does the sweetening instead of sugar.
- Add the garlic and chiles and simmer for 5 minutes to build the base.
- Add the tomatoes and okra and simmer for 5 minutes, until the okra is tender and the tomatoes start to slump. The okra also lightly thickens the broth.
- Slide in the tofu and simmer gently for 2 minutes, just to heat it through.
- Turn off the heat. Stir in the tamari, the lime juice, and the bean sprouts. The sprouts should stay crunchy, so residual heat is all they need.
- Ladle into bowls and pile on the cilantro and scallions. Taste one more time and add lime for sour or tamari for depth.
