Instructions
Parboil
Add the pork soup bones and pig trotters to a large pot, cover with water and salt heavily. Bring to a boil to parboil and release all the scum.
Drain, then clean the bones and trotters thoroughly under running water. Add them back to a clean pot with clean water.
Make the broth
While the pot heats, peel the daikon and cut it into large chunks. Soak the dried shrimp in water; they help sweeten the broth. Add the dried squid as well.
Add everything to the pot along with 1 whole white onion. Add salt and bring to a boil.
Once boiling, skim the foam from the top. Lower the heat and simmer.
After two hours, take out the pig trotters and let them cool in a bowl of cold water.
After another hour, remove the bones and everything else from the broth.
Add more water as needed and season with fish sauce, sugar, chicken powder and salt to taste.
Prep the toppings
Cut the cooked pork blood into cubes and slice the fried fish cakes.
Cook the bánh canh noodles according to the package, then drain.
Assemble
Before serving, blanch the noodles, trotters, fish cakes and blood cubes in the hot broth to warm them through, then add to a bowl.
Garnish with green onion, fried shallots and cilantro, crack fresh black pepper over the top, and ladle in the hot broth.
Notes
Pork blood: I buy raw pork blood at 99 Ranch and cook it into cubes, or look for pre-cooked blood cubes at Asian grocery stores.
