  3. Remove the beef shank from the pot. Transfer to a bowl of cold water. Then thinly slice the beef shank. 

Making the spicy soup paste

  2. Reduce heat to low, add in Hue seasoning powder and chili flakes. Turn off heat.

  3. When the broth is done, add in the spicy soup paste to the broth. Taste the both again according to your taste preference.
