Egg drop soup is a Chinese dish that combines the savory flavors of egg and chicken broth into a warm, comforting soup. Traditionally, this soup has added cornstarch (to increase thickness), but this recipe calls for xanthan gum. Xanthan gum is a high-fiber, low-carb alternative to flour or cornstarch to thicken a soup without adding extra carbohydrates. This content is only available to members.
