4 cups water
1 pound lean ground beef, marinate with salt, pepper, corn starch and 1 egg for 30 minutes
Bring water to a boil in a pot. Add chicken stock and corn and bring back to a boil.
Add marinated ground beef, break them up with a pair of chop sticks before dropping into the boiling soup and stir to further prevent it from clumping together. Let simmer for 10 minutes.
Thicken the soup with some corn starch solution until your desired thickness.
