Egg drop soup is a very popular Chinese take-out soup along with hot and sour soup and wonton soup. It's made with a lightly seasoned chicken broth, thickened to a velvety consistency, and is known for its iconic yellow color and wispy egg drops (egg flowers). This is the perfect soup to make for a light meal, taking only 10 minutes, or when you're under the weather. Plus, it's also naturally gluten free.
