How to choose fresh ingredients
How to choose good tofu, free from gypsum
- Tofu made from soybeans usually has an off-white color, with a distinctive pleasant aroma from soybeans.
- You should choose tofu that still feels elastic and smooth when pressed.
- Tofu mixed with gypsum is often very hard, has a pure white color, and has no smell or has a sour, strange smell.
- Avoid buying tofu that feels slimy to the touch or has turned yellow, as this indicates spoiled tofu.
How to choose good, sweet pineapple
- Based on color: Choose fruits that have an eye-catching yellow color, sometimes mixed with green. Avoid buying fruits that are unevenly ripe, especially those that have turned brown as they are overripe and about to spoil.
- Based on shape: Short, round fruits usually have more flesh than elongated fruits. Choose pineapples with larger eyes, as these are naturally ripe fruits and will not lose much flesh when peeled.
- Based on aroma: Fruits that have a sweet, not too strong smell are perfectly ripe and ready to eat. If you smell a very strong aroma, it indicates overripe fruits that spoil quickly and may undergo natural fermentation.
- Based on touch: A perfectly ripe pineapple will have slightly wrinkled skin, and pressing it will feel moderately soft. If it feels hard and heavy, it indicates unripe fruits.
How to Make Sour Soup with Clams and Tofu
-
Prepare the Ingredients
Clams should be scrubbed vigorously and soaked in salty chili water for about 3 hours to allow them to expel all the sand and mud, then scrub the shells clean and rinse several more times.
Tofu is cut into bite-sized cubes. Tomatoes, bamboo shoots, and fresh lemongrass are thoroughly washed. Cut the tomatoes into wedges, peel the bamboo shoots and slice them thinly, then crush and shred the fresh lemongrass.
Shallots are washed, roots removed, and minced. Fresh herbs should be torn into small pieces and soaked in diluted salt water for about 10 minutes. Pineapple, which has already been peeled, is simply sliced thinly into a fan shape.
-
Boil the Clams
Place a pot with 200ml of cold water on the stove, add 400g of clams and all the shredded lemongrass to boil for about 10 minutes; when the clams open their shells, turn off the heat.
Next, scoop the clams onto a plate to cool, then separate the clam meat into a bowl.
-
Cook the soup
Place another pot on the stove and heat 1 spoon of cooking oil over medium heat. When tiny bubbles appear, add the minced shallots and stir well until fragrant and golden for about 2 minutes, then add tomatoes and pineapple and stir for another 3 minutes.
Next, add about 200ml of clam broth and 100ml of water to the pot and bring to a boil for about 5 minutes.
Mash the sour tamarind with a little hot soup water, then take the tamarind juice and add it to the boiling soup along with 1 tablespoon of sugar and 1 tablespoon of seasoning, then stir well.
Finally, add tofu, clam meat, water morning glory, cilantro, and Vietnamese coriander, stir gently, and cook for another 2 minutes to finish.
-
Final product
The sour clam soup with tofu, featuring eye-catching colors and an incredibly enticing aroma, is ready! The broth is clear and mildly sweet, with a fragrant clam flavor and a refreshing sourness from the vegetables. This soup paired with hot rice is simply unbeatable!
How to choose fresh clams (ngheu)
- First, you should check and choose clams that are tightly closed because most of them are fresh and alive. To be more thorough, you can try to open the clam shell with your hands; if it opens easily, it means the clam is dead.
- You should buy clams with a sturdy shell that is not chipped, and choose clams that are large enough to hold firmly in your hand because they have more meat, and they will taste better and sweeter after cooking.
- You should not buy clams that are too small because after cooking, the clam meat shrinks, is not sweet, and reduces the deliciousness of the dish.
- Additionally, you should not choose clams that have an unusual fishy smell because there are certainly dead clams among them, which affects the flavor of the dish and the health of the consumers.
Quick tips for cleaning sand from clams
- Soaking in water with rice and fresh chili is an effective way to clean clams; however, this method takes quite a bit of time. Instead, using warm water at around 50 degrees Celsius will clean the clams of sand more quickly.
- In water at 50 degrees, clams will feel threatened and will protect themselves by absorbing more water, thus accelerating the sand expulsion process. Usually, it only takes 10 minutes to have clean clams ready for cooking.
- However, this method requires the appropriate temperature; otherwise, the clams will cook.
