Understanding the Role of Tamarind

The magic ingredient that gives Canh Chua its signature taste is tamarind. This pod-like tropical fruit has an intensely tart and slightly sweet flavor that forms the flavor base of the broth.

When buying tamarind, look for pliable pods free from mold. Avoid hard or dried out pods. Tamarind paste is the easiest form to use. Dissolve it in hot water to extract the sour juice.

Start with 2-3 tbsp tamarind paste and add more to taste. The juice not only provides acidity but also helps tenderize the fish thanks to enzymes like amylase.
