Tools Required
How to Choose Fresh Delicious Freshwater Crabs
- Choose freshwater crabs that have a dull purple-gray color, with the shell being lighter in color. To choose crabs with more meat, select male crabs with a small and pointed abdomen, while for crabs with more roe, choose female crabs with a larger abdomen, often referred to as “flower abdomen.”
- Choose those that still move quickly, with claws and legs intact and flexible. Pressing on the abdomen shell and seeing bubbles form means the crab is still fresh.
- To make delicious crab noodle soup, crabs must be pounded by hand; the crab meat foam will be soft and smooth and retain its characteristic flavor. If you don’t have time, you can grind the crabs using a blender, but the crab meat foam is often airy and gritty.
- Avoid choosing freshwater crabs with red eyes, those with hairy undersides, or those with star-shaped spots on their backs.
How to Prepare Fresh Crab Noodle Soup
-
Prepare the Fresh Crab
Soak the crabs in water for about 1 hour to remove all dirt and sand, then rinse with clean water. Remove the crab’s apron and shell, and set them aside.
Use a small spoon to scrape the crab roe into a bowl, seasoning it with a little ground pepper and seasoning. Grind or pound the crab apron into small pieces.
Put the ground crab into a large bowl, season with a little salt, then add water and gently squeeze with your hands to dissolve the crab meat into the water. After that, use your hands or a sieve to filter out the crab remnants and collect the liquid. You should have about 3.5 liters of crab broth.
-
Prepare Other Ingredients
Pork fat should be cleaned, cut into small square pieces, and then fried until golden (use the pork fat for cooking the other ingredients). Cut the tofu into small pieces and fry until golden.
Wash the green onions, chop half into small pieces and cut the other half into about 3cm lengths. Peel and slice the shallots.
Wash the tomatoes and cut them into wedges. Blanch the pig’s blood in water to clean it, then cut it into bite-sized pieces.
Soak dried shrimp and dried squid in water for about 30 minutes, then cut the squid into small pieces and fry it golden with the dried shrimp.
-
Fry shallots
Add 150ml of cooking oil (or use the pork fat if there’s plenty) into a deep pan, heat it up, then add the sliced shallots and fry until golden.
Once the shallots are golden, add the crispy pork fat and fry briefly, then remove and drain.
Tips for frying crispy shallots, without oil splatter
- Add 3 – 4 drops of lemon along with a little salt when the oil is not yet hot, wait for the oil to heat up then add the shallots, this way the shallots will be crispy and not splatter oil.
- Use an appropriate oil ratio, about 600ml of oil for every 500g of shallots. This ensures the shallots are submerged in oil and crispy all over without burning.
- Add the shallots gradually instead of pouring them all at once, while continuously stirring gently with chopsticks to avoid the shallots breaking apart.
-
Stir-fry crab meat
Take the separated crab meat, add it to the pan with 1 tablespoon of pork fat and stir-fry until cooked.
-
Make and steam the crab cake
Put 100g of crab meat, 2 egg yolks, 1 teaspoon of seasoning, a little chopped green onion along with some filtered crab broth into a bowl and mix well.
Then pour this mixture into a mold along with about 100ml of filtered crab broth and steam for about 30 – 40 minutes until the crab cake is cooked.
You spread some sautéed crab meat on the surface of the crab cake to create an eye-catching golden color and enhance the flavor.
-
Sauté tomatoes
Heat a pan over the stove with a little lard, add the tomato wedges and 1 tablespoon of annatto oil to sauté for about 5 minutes.
-
Making the broth
The pre-fried squid and shrimp are put into the pot, along with the crab shells carefully wrapped in cloth. Add 1.5 liters of water to the pot and cook for about 30 – 40 minutes so that the shrimp and squid release their sweetness.
Remove the shells; at this point, there should be about 1 liter of broth left in the pot. Continue to pour in 3 liters of filtered crab soup and simmer on low heat so that the crab soup gradually forms a layer of meat and floats to the surface.
Then add the tomatoes, tofu, blood pudding, chopped green onions, and remaining crab fat into the pot, seasoning with: 60g of sugar, a little monosodium glutamate, 20ml of fish sauce, a bit of seasoning powder, pepper, and 20g of shrimp paste, stirring well.
Tip: Shrimp paste creates the distinctive flavor of crab noodle soup; if you don’t like it, you can omit it.
-

How to choose fresh and delicious pork
- You can buy pre-ground meat or buy whole pieces of pork to grind yourself or use a blender for better safety.
- Select pieces of meat that have both lean and fat so that when eaten, it has a delicious fattiness, not too dry.
- Choose pieces of meat that are bright pink and fresh. Press your hand on it and feel the meat’s elasticity and firmness, which should stick tightly together.
- Do not choose pieces of meat that are pale green, darkened, or have small white spots in the meat; these could be from dead pigs, stored for too long, or sick pigs, tapeworms.
- It is advisable to choose reputable food stores with clear origins to ensure the best meat quality.

How to choose fresh and delicious pig trotters
- Choose the hind legs of the pig as they usually have more meat and higher nutritional value.
- Good quality trotters usually have good elasticity, with the hooves intact.
- Trotters with unusual colors such as green or purple, or with abnormal fluids leaking out indicate that these are from sick pigs that have been injected with antibiotics or from pigs that have died for a long time; absolutely do not buy them as they can affect consumer health.
- It is advisable to buy pig trotters at reputable supermarkets or food stores to ensure the quality of the trotters.
How to prepare pig trotters without odor
- After purchasing, use a knife to scrape off the hair, then rub salt to eliminate the odor, and rinse with clean water.
- Then blanch the trotters in boiling water with minced shallots and ginger for about 1 minute to remove dirt and odor.
- Additionally, you can soak the pig in diluted saltwater, adding lemon or vinegar, and smashed ginger will also effectively eliminate odors.
