Canh Chua Vietnamese Sour Tamarind Soup


From Tebetian highlands to the lowlands of southwest Vietnam, the Mekong river and it’s thousands of tributaries meanders it’s way across 39,000 square km in Vietnam known as the Mekong Delta or miền tây (western region) , encompassing the lands immediately west of Saigon to the very southern tip, Cà Mau.


Dubbed as a biologic treasure trove, the waters of Mekong river is a way of life for over 17 million inhabitants. It’s waters and rich soil help to produce half of the countries rice crop each year as well as an abundance of fruits. It’s also home to large aquacultural industry raising catfish, basa, and shrimp.


Life here revolves around the river–owning a boat is just as important as a scooter, if not more, as it means you can ferry your crops to the market to sell to earn a living. The Cái Răng market in Cần Thơ, is one of the largest floating markets in the region. Mainly a wholesale market for fruits and vegetables, this normal way of life has become a must see destination for anyone visiting this area.


Each morning at sunrise, the market is teaming with activity. Hundreds of large wholesale boats from all over delta converge and drop anchor in the market, hanging their crops on bamboo poles to signal what’s in season and for sale.  We’re not sure if there’s any order to it all–bananas on one end or dragon fruit on the other, but the the large boats create lanes, or market aisles if you will, for smaller retail boats (and tourists boats) to weave through. Instead of aisle numbers and shopping carts, check the bamboo poles weave your boat to your vendor, place your order and soon bundles of fruit and vegetables are tossed onto your boat. It’s an extraordinary way of doing business that you’ll ever experience.


If you see household items on the boat such as cloths or pots and pans, or even pets on boat it doesn’t mean it’s for sale. Some families actually call the boats home!


As with markets on land, there’s no shortage of food options to satisfy all the hungry vendors and visitors. You can flag down floating cafes to indulge your cafe sua da morning fix as well as banh mi boats to satisfy your breakfast cravings.


Oh, but you’ll rather have a bowl of hủ tiếu instead? No problem! There’s a boat for that too. Just good luck trying to eat a bowl of noodles in a floating boat.  After you manage that, the noodle lady will navigate around find you and retrieve her bowl and chopsticks. The ingenuity and perseverance of these people are simply amazing.

canh chua

But the Mekong Delta isn’t known for hủ tiếu or even pho for that matter. It’s known for dishes that uses the abundant seafood and vegetables from the region such as hot pots called lẫu mắm made from salted fish as well as one of our favorite soups, canh chua. We adore canh chua because the contrasting flavors of sour, sweet, and savory and we also love the contrasting textures of all the different vegetables. Literally translated as sour soup, canh chua combines all the wonderful abundance of this region, incorporating seafood (such catfish, snakehead, eel, shrimp among others) along with colorful medley of tamarind, pineapple, tomatoes, okra, elephant ears, bean sprouts and a variety of herbs such as lemony ngo om. Enjoy canh chua with some steamed jasmine rice as part of a traditional Vietnamese meal or alone with some rice vermicelli noodles.

Everytime we make this dish, we’ll always remember the floating fruit vendors and  life on the Mekong.  If you’re visiting, hire a private small private boat to visit the market early around sunrise or slightly after when it’s most busy.
