Once the chicken broth starts to boil, adjust the heat to medium-low and add in 2 slices ginger, and 2 cups corn.
Add in 2 ½ tablespoons miso paste and stir the soup a few times to dissolve it.
Let it simmer for 10 minutes on a low simmer.
Thicken the Soup with a Cornstarch Slurry
After 10 minutes of simmering, bring the heat back up to medium heat.
In a small bowl, mix together 3 tablespoons corn starch with 4 tablespoons cold water.
Pour the starch slurry into the soup slowly while stirring. Keep stirring until the soup has thickened.
Make the Egg Ribbons
In the same bowl, you used to make the cornstarch slurry, beat 2 eggs with a fork or chopsticks until they are well mixed.
Once the soup has come to a simmer again, stir the soup in 1 direction a few times to create a whirlwind effect and turn off the heat.
Slowly add the egg mixture in while continuing to stir. Keep stirring in the same direction slowly for 1 minute until you see egg ribbons and the eggs are cooked.**Do not use a whisk to do this step. Use chopsticks or a wooden spoon to gently mix the egg mixture into the soup.
(Optional) Mix a few drops of sesame oil to the soup for some additional sesame flavor
Find the ginger slices, and discard them before serving.
Enjoy!
Notes
Transform this soup into a meal by adding cooked rice or noodles in once the soup is done
You can also add a can of cream of corn for extra flavor.
If you don't want to use miso, you can omit it and use 1 and ½ teaspoons of salt instead. Do a taste test, if it's not salty enough add some more.
