Vietnamese sour shrimp soup (canh chua tôm) is a refreshing and flavorful soup of the Southern region of Vietnam. This dish is an excellent addition to family dinners with its balanced sweet and sour taste. My version emphasizes the natural sweetness of shrimp and minimizes the use of added sugar.
Canh chua tôm features succulent shrimp, pineapple, tomatoes and veggies in a sweet and sour tamarind-based broth. The Southern region of Vietnam is hot all year round, and this refreshing and tangy soup helps to stimulate the appetite and complement the rice well.
Make A Good Shrimp Stock
The taste of sour soups varies quite significantly between the North and South of Vietnam. As someone from the North, I often find Southern restaurants are a bit too heavy-handed with the amount of sugar, to the point that I sometimes feel like maybe they should call the dish sweet shrimp soup instead. So, for my version, I minimize the amount of sugar added by making a good homemade shrimp stock.
I have a more detailed post on how to make shrimp stock here. Made from simmering shrimp heads and shells, the stock adds depth, complexity and natural sweetness to the soup. Shrimp stock is also a great base for Vietnamese shrimp vermicelli noodle soup.
The sourness of this shrimp soup primarily comes from tamarind paste. The addition of pineapple and tomatoes adds a natural sweetness and slight tanginess, and it also enhances the overall flavor profile. It’s not uncommon to see pineapples in Vietnamese savory dishes, as you may have seen in this stir-fried squid recipe.
You can find tamarind paste or concentrate packed in a jar at grocery stores or Amazon. The taste and consistency may differ among brands so you may need to adjust the amount to your liking. Just make sure you buy either Thai or Vietnamese paste, and not the Indian one. In Vietnam, we can buy tamarind pulp to make our own paste.

Vegetables and Herbs
With an abundance of fresh produce, Southern Vietnamese people love to add a lot of veggies to their sour soups. The common additions include okra, bean sprouts, and taro stems. You can add all of them or just pick one type that you like. For me, I’m happy with adding just bean sprouts.
This Vietnamese sour shrimp soup also includes a lot of herbs which add a refreshing aroma and a cooling sensation. Chopped scallions, saw-tooth leaves (ngò gai) and rice paddy herbs (ngò om or rau ngổ) are traditional choices. You may also use cilantro and Vietnamese coriander, depending on what you can find at your local Asian grocery stores.
