The linh fish you buy should be cleaned, scaled, and have the fins and tail removed. Use scissors to cut open the belly, then clean out the intestines. After that, rinse the fish thoroughly with water and let it drain.
Be careful when gutting the fish to avoid breaking the bile sac, as a broken bile sac can make the fish taste bitter.

Prepare the vegetables
The water lily flowers should be peeled and cut into bite-sized pieces, and the water lily stems should have any bad flowers and old stems removed. Rinse all vegetables, soak in diluted salt water for 10 minutes, then rinse with clean water and let them drain.

Make tamarind juice

Boil fish
Add 1.2 liters of water to the pot and bring it to a boil. Once the water is boiling, add the fish and season with 1 teaspoon of salt and 3 tablespoons of sugar. Wait for the water to boil again, then lower the heat to prevent the fish from breaking.

Cook the soup
Cook until you see the fish floating evenly, which indicates it is cooked. At this point, use a ladle to remove the foam to keep the soup clear. Cook for another 4 minutes to ensure the fish is evenly cooked, then add the water lily.
Then, add 50ml of tamarind juice, 2 tablespoons of fish sauce, and 1/2 teaspoon of MSG. Wait for the water to boil again, add the water lily, season to taste, and turn off the heat.
Tip

- Choose pineapples that have a bright yellow color from the crown to the tail, with a few eyes that are slightly green, as these are ripe fruits that will be sweet and delicious.
- Choose round, short pineapples as they will have more flesh compared to long-shaped ones.
- Choose pineapples with large, sparse eyes, as this indicates that the pineapple is mature and naturally ripe, not chemically treated.
- You can try smelling the end of the fruit; if it has a fragrant smell, then you should buy it. Additionally, avoid choosing fruits that have a slightly sour smell, as this indicates that the pineapple is overripe.
- The greener the pineapple crown, the fresher it is. Overripe pineapples will have dry or brown tips.
- Choose fresh, tasty pineapples that are neither too hard nor too soft; when you press your finger into them, they should not feel indented.
How to choose fresh okra
- Choose fresh, young okra pods that are small in size, have a beautiful glossy green color, and a thin layer of fuzz on the outer skin.
- Do not choose pods that are soft or have bruises on the outside, as well as those that are too large, as they will be old and not tasty.
- Press lightly with your hand; if the skin feels crisp and hard, not soft and indented, then it is fresh, young okra.
