You can use pre-prepared vegetable broth. If you'd like to create your own, though, add 3 carrots, 3 cloves garlic, and 3 green onions to a large pot with 8 cups of water. It can help to loosely chop the produce. Although you can add it whole.You can use any produce that you want. A lot of people keep the ends of produce in an airtight container in the refrigerator just to make broth. I tend to cook a lot of my vegetable scraps into pet food and don't have an abundance of freezer space. But this is also an option! Otherwise, add whatever produce you want to flavor the broth.If you want to do a meat version of this recipe, I'd recommend adding in chicken or beef bones and simmering on the longer side.
Simmer until reduced in half. This can take 1-3 hours, depending on how hot your stove simmers on.
Strain the produce out of the broth and return to the pot on the stove.
Cook Soup
Add vegetable broth to a large pot and bring to a simmer over medium heat.
In a small bowl, thoroughly mix the cornstarch and water together.The amount of cornstarch will determine the final consistency. Use more cornstarch for a thicker soup. Use less cornstarch for a thinner soup.
Drizzle the cornstarch slurry into the large pot of simmering water. Making sure to mix constantly into the broth.
Add Eggs
Lightly beat the eggs.
There are a couple of different ways to add eggs to the egg drop soup. You can rapidly stir the broth and then slowly drizzle the egg in (much like you would for poached eggs, only you want the egg to be stringy. Hence pouring it, instead of dropping an entire egg in).Alternatively, slowly pour the egg into the broth over a ladle or chopsticks. Either way, the goal is to produce "egg flowers," or swirls of eggs that are intermixed throughout the soup. You can add more at a time for a larger flower and less at a time for a smaller flower. Basically, tell everyone that what you ended up with is what you were going for and then adjust next time to personal taste!
Mix in a little sesame oil, salt, pepper, and green onions to serve.
