Preparing Dried Shrimps

Wash dried shrimps then place them in the tea ball strainer. Set aside.


Cooking Pork Stock

If using pork neck bones, ask the butcher to cut it into about 3 inch chunks. If  using spare ribs, have them cut into 2 inch pieces.

Blanching pork bones: this step is to be done before boiling to remove any impurities from the bones. In a 8-quart stockpot, cover the bones with cold water, bring to a boil. Cook for a couple more minutes before draining. Remove the bones. Rinse under running cold water. Discard the blanching water.

Cooking Broth: Cover the pork bones again with water. Add onion and garlic. Drop the dried shrimps tea ball strainer in the pot with the hanger hangs from the side of the pot. This is how I soften the dried shrimps and also add a bit more depth and complexity to the flavor. Bring pot to a boil, then reduce to a simmer until the meat is cooked through, at least 45 minutes. Frequently skimming any additional foam, and debris from the surface. Add more water if needed. You can make the stock a day ahead.


Cooking Noodle

Cook noodle according to the package instructions. Set aside.


Preparing Crab and Shrimps Paste

Remove dried shrimps tea ball straining from the broth pot.   

Place dried shrimps in a food processor and process finely. Set aside.

Place shrimps and white parts of green onion in a food processor and process finely.

In a mixing bowl, combine dried shrimps, shrimps, crab meat, eggs, onion powder, garlic powder, pepper, sugar, and salt. Mix well.


Preparing Tomatoes

Cut tomatoes into wedges. If used cherry tomatoes, cut each one into half. 

In a skillet, heat a tablespoon of olive oil and a teaspoon of annatto seeds (aka achiote seeds) over medium heat, and cook, stirring constantly, until the oil becomes a rich, orange-red color, about 2 minutes. Discarding the seeds. The purpose of using annatto seeds is to give the broth its distinctive red color. You can skip the annatto seeds if preferred.

Add shallot and garlic to the annatto oil and cook until fragrant. Add half of the tomatoes and cook until soft.


Cooking Bún Riêu Broth

Liquid a tablespoon of shrimp paste with a couple tablespoons of pork stock. Set aside. 

Turn up the heat on the stock pot to a rolling boil. Scoop a spoonful of the crab mixture at a time and drop it into the stock. The crab balls will float to the top once cooked.

Turn the heat down to a medium. Season the pork stock with fish sauce, sugar, salt, and shrimp paste mixture. Add the cooked tomatoes, fresh tomatoes and fried tofu cubes, if used, to the stock pot. Adjust the seasoning to achieve the balance of savory, slightly salty, and natural sweet of broth. Simmer the broth for a little longer, about another 10 minutes.



Add noodle to a bowl. Ladle in the soup, pork, crab meatballs, and tofu cubes, if used. Garnish with chopped cilantro and green onion. Serve with shredded iceberg lettuce, or curled stem of water spinach, bean sprout, assorted herbs, and a squeeze of lime or lemon and you are ready for a slurping good time.
