Years ago, it was quite hard to find all of the required ingredients to make this authentic soup. However, it is much easier to find those ingredients due the popularity of Asian cuisine worldwide now.
This classic Vietnamese soup is often paired with catfish clay pot besides a bowl of hot steamed rice. That being said, you normally find both of these dishes served together in any Viet family meal.
For soup base:
- Catfish bones - to make the broth. If catfish bones are not available to you, store bought seafood/fish stock will do the job.
- Tamarind soup base - I use Knorr tamarind mix and it works perfectly
- Fish sauce - Red Boat brand has always been my number one choice
- Sugar - I use white granulated sugar or even better palm sugar
For hot & sour shrimp soup main ingredients:
- Shrimps or prawns - washed, peeled, and deveined
- Okra - keep them whole or halved. The broth might get slimy if you cut okra into multiple small pieces
- Elephant ear plant stems - or taro stems/ bac ha. Peeled and cut into pieces
- Bean sprouts - you can easily grow bean sprouts at home with these tips
- Whole tomatoes - cut into pieces
- Pineapples - cut into bite size pieces
- White cabbage - this ingredient is totally optional.
- Rice paddy herb - chopped
- Thai red chilies - keep them whole or slice into small pieces
- Fried garlic - don't skip this ingredient. The fried garlic adds such a good aroma for the soup.
Tips to make the best hot & sour shrimp soup
The main taste of this soup should lean toward the sourness followed by the sweetness. Fish sauce & salt are here to help balance the taste not to over power the other two.
So in order to make the best soup, you should never use more than the recommended amount of fish sauce. If you need to adjust the saltiness, always use extra plain salt. Because too much fish sauce can compromise the main tamarind taste.
Remember a little seasoning goes a long way, adjust with a few pinch salt or sugar at a time. Wait for them to dissolve completely, taste, then add more if necessary.
Blanch and plunge vegetables into an ice bath then set aside. Blanching helps preserve their freshness, original color, and nutrition. When you're ready to eat, heat the soup broth on the stove then add blanched veggies after. This way you get control over the vegetables more.
It's easy to overcook those greens which are already very delicate to begin with. You can still cook the vegetables directly in the pot, just make sure to keep an eye on them because they're cooked pretty quickly. It normally only takes 2 minutes to fully cook them.
It is best to make the soup broth separately so you can keep it for 2-3 days under refrigeration or 2 weeks in the freezer.
If you add protein & vegetables in the soup then it is best to serve within 1 day.
