Step by step

Method

5 steps

1. 1

   Rinse the beef bones, then simmer them with onion, ginger, cinnamon, and water for about 20 minutes. Skim any gray foam so the broth stays clear.

2. 2

   Soak or cook the rice noodles according to the package directions. Drain when they are tender but still springy.

3. 3

   Strain the broth if you like, return it to the pot, and season with fish sauce. It should smell warmly spiced and taste savory, not harsh.

4. 4

   Divide the noodles among bowls and pour over the hot broth. Add thin-sliced beef if using and let the heat cook it through.

5. 5

   Finish with herbs, bean sprouts, lime, and scallions. Taste a spoonful with lime before adding more fish sauce.
