In a small bowl, combine the 1 ½ tablespoon of corn starch and 1 ½ tablespoon chicken stock together. Whisk until corn starch is dissolved into the chicken stock.
In another small bowl, crack your 2 large eggs and beat the egg whites and egg yolk together until smooth.
On a stove top oven, heat up your soup pot on medium heat. Add your cooking oil to the pot and add your onion to the pot. Cook the onion until it is soft and translucent.
Add 2 cups of chicken stock to the pot. Turn the heat up to high to let the chicken stock boil. Once the chicken stock boils, you will slowly pour your corn starch mixture into the pot. Be sure to keep stirring the broth in the pot with a spoon as you're pouring the corn starch mixture to prevent clumping.
Next, slowly add in your beaten eggs while stirring the broth in the pot with a spoon (like how you did with the corn starch) to prevent clumping.
Turn off the heat. Add salt. You can add black pepper or more salt to your desired taste.
