Step 1

Bring the broth to a simmer in a medium saucepan over medium heat. (The broth should be about 2 inches deep in the pan.) Add the star anise and cinnamon and simmer for 5 to 10 minutes to infuse the broth with the spices. When finished, use a slotted spoon to remove the spices.

Step 2

Crack the eggs into separate measuring cups and slip them into the simmering broth, one at a time. Cook for 2 minutes, then add the noodles and bok choy. Stir very gently to submerge the noodles and bok choy, but so as not to break the eggs. Cook for another 2 minutes, until the whites of the eggs are completely set but the yolks are still loose. (Cook for an additional minute if you like your yolks set.)

Step 3

Off the heat, gently stir in the soy sauce and the scallions. Taste and add more soy sauce if needed. Divide the soup between 2 bowls and eat immediately.
