How to choose fresh ingredients
How to choose good basa fish
For frozen basa fish:
- You should buy from reputable stores or supermarkets.
- Choose fish that is stored in vacuum-sealed bags, kept at a temperature from -20 degrees Celsius to ± 2 degrees Celsius to ensure the quality of the fish meat after purchase.
For live basa fish:
- You should choose healthy basa fish swimming in water or fish just caught from the water with scales intact and firm.
- When pressing with your hand, the fish meat should feel firm and not mushy.
- The fish’s eyes should be clear, not bulging or sunken.
- Note that when buying fish, you need to pay close attention to the length of the whiskers and the characteristics of the flesh to avoid confusing basa fish with tra fish (tra fish have equal whiskers and relatively thick flesh with a slightly pink color, while basa fish have differently sized whiskers and smaller, even flesh that is white).
How to choose fresh octopus
- You should choose octopus with clear eyes, a bright white belly, and smooth, fine skin on the back. When you touch the body, it should feel firm and not slimy.
- If buying live octopus in a tank, choose those that are still swimming, and when taken out, they should move more actively than the others.
- For frozen octopus, you should choose octopus with a gray-brown color on the back and a bluish sheen, with bright white flesh underneath, and the body should not be swollen.
How to choose good pork belly
- To buy good pork belly, you should choose a piece of meat with a balance of lean meat and fat, a thick outer skin, fat about 2/3 of a finger’s length, and the lean meat tightly attached to the layer of fat. However, it is important to note that to buy pork belly that is just right to eat, not too chewy, you should not choose a piece of meat with an outer layer of fat and skin that is too thick because that is from a pig that has been raised for a long time.
- In addition, fresh pork belly will have a dry outer membrane, light red or bright pink color. When cut, the piece of meat has a bright pink color, white-pink skin, and is soft. The fat interspersed with the lean meat is bright and firm.
- Absolutely do not buy pork belly that has an unusual smell, has cysts shaped like a loquat (fruit flies) lying parallel to the meat fibers or small white spots because that is meat that has been infected with parasites and larvae.

How to Prepare Fermented Fish Hot Pot

Prepare Fresh Ingredients
After purchasing the pork belly, rub it with salt, then rinse it thoroughly with water and cut the meat into small bite-sized pieces, about 1/2 finger length.
For the shrimp, remove the head, legs, and antennae, then rinse them in diluted salt water for about 1 minute before rinsing again with clean water.
For the basa fish, rub it with salt and rinse with clean water to reduce the sliminess. Then soak the fish in diluted lemon juice or water mixed with a bit of vinegar for about 5 minutes to eliminate the fishy smell. Next, cut the fish into small pieces, about 1 finger length.
Next, use a knife to cut the octopus’s head in half to remove the beak and ink sac. You can push the octopus’s beak out by gently squeezing its mouth until the beak appears, then cut it off.
Finally, rinse the octopus again in water mixed with vinegar, alcohol, or crushed ginger to eliminate the fishy smell. Then, place the octopus on a cutting board, hold one tentacle up, and cut it close to the body. Do the same for the other tentacles.
Tip: If you are using frozen octopus, after purchasing it, you should place the octopus in the refrigerator for about 24 hours to thaw it properly! -
Prepare dry ingredients
Eggplant bought should be washed clean with water, then cut into pieces about 2.5 finger lengths and split in half.
As for bitter melon, wash it with water, remove the seeds, and cut into small pieces about 1/2 finger length.
Then soak the eggplant and bitter melon in diluted salt water for about 5 – 10 minutes, then take them out to drain.
Next, take shallots, garlic, and half of a chili pepper, wash them clean, then put them into a food processor to grind them finely. You can also chop them finely with a knife and cutting board.
For the lemongrass stalks, wash them clean, slice them thinly, and then divide them into two equal parts. The first part goes into the food processor to be ground finely, and the second part you put into a small bowl with sliced chili pepper, then add 1 tablespoon of good fish sauce to make a dipping sauce.

How to Choose Fresh Ingredients
How to choose fresh shrimp
- When choosing shrimp, you should select those with a transparent shell, avoiding shrimp that have dark patches or inconsistent colors.
- Choose shrimp with tails that are tightly closed together; if the tails are spread out, the shrimp may have been injected with chemicals or water.
- If you lift the shrimp and notice a slimy texture, and the body is curled into a circular shape, avoid buying them. If you press lightly on the shell and feel bumps like grit, do not purchase.
How to choose fresh water spinach
- Choose bunches of water spinach with stems about the size of a rice eating chopstick, with small tops and slightly firm appearance.
- To purchase fresh water spinach, you should go to the market in the morning as this is when the vegetables are freshly picked and very fresh.
- Avoid choosing water spinach that looks overly lush; when breaking the stem, it should be crisp, and the leaves should be dark green, with unusually large stem sizes.
How to choose fresh and delicious lemongrass
- Choose lemongrass with tightly wrapped leaf sheaths, with older stalks surrounding the younger ones inside and having a distinctive aroma.
- Select lemongrass with leaves that are not wilted and have a beautiful green color.
- Avoid choosing lemongrass that is wilted or damaged as it will have less fragrance.
How to choose delicious and quality shrimp paste
- Delicious shrimp paste will have a distinctive aroma, a sweet and rich taste, not pungent or bitter.
- Choose shrimp paste with colors ranging from bright pink to reddish-brown, without any unusual odors.
- You can buy shrimp paste at reputable stores and supermarkets. When purchasing, be sure to carefully check the origin, expiration date, and whether the packaging is intact.
How to preserve dishes
- When eating, you should scoop out just enough to use. If there’s leftover broth, you shouldn’t pour it back into the main pot as this can cause the broth to spoil easily.
- For squid and shrimp that are not used, you should place them in a specialized food storage bag and keep them in the freezer.
- Note that you should store them for a maximum of 2 days in the refrigerator; keeping them longer can cause the dish to spoil and produce toxins that are not good for health.
