2. Ingredients: The Heart of Sweet and Sour Fish Soup

The magic of Canh Cá Sốt Chua Ngọt lies in its carefully chosen ingredients, each playing a vital role in building layers of flavor.

Key Ingredients

1. Fish: Fresh fish is the star of this dish. Commonly used varieties include snapper, grouper, or tilapia, as their firm flesh holds up well in the soup. For a richer taste, you can use fish with higher fat content, such as mackerel or salmon.
2. Tamarind Paste: Tamarind is the source of the soup’s tangy flavor. It adds a bright acidity that balances the sweetness and enhances the natural taste of the fish.
3. Tomatoes: Fresh, ripe tomatoes provide a subtle sweetness and give the soup its characteristic red hue.
4. Pineapple: Adding pineapple lends a natural sweetness and a tropical aroma to the dish, complementing the tanginess of the tamarind.
5. Aromatics: Garlic, shallots, and lemongrass form the base of the soup, contributing depth and fragrance.
6. Vegetables: Popular additions include okra, bean sprouts, or water spinach, which add texture and nutritional value.
7. Herbs: Fresh herbs such as cilantro, Thai basil, and sawtooth coriander are used as garnish, providing a burst of freshness.
8. Seasonings: Fish sauce, sugar, salt, and black pepper are essential for seasoning, ensuring a balance of flavors.
