Heat a kadai and put 2 tsp of ghee (clarified butter) in it. When it is hot put 1 tbsp each of finely chopped ginger and garlic in it. Fry them slightly for a couple of minutes on a medium flame. (Pro tip: Fry the ginger and garlic until they become soft and translucent but make sure the color of the garlic does not change as it will alter the taste of the soup).
Now, to make the soup nutritious, add ¼ cup of carrot (finely chopped) and ¼ cup of beans (finely chopped) to it. Sauté them for about 2 to 3 minutes on a high flame. (Pro tip: In addition to carrots and beans, you can use other vegetables of your choice as well such as cabbage, mushroom and others but do not add too many vegetables because you are not making a vegetable soup).
Now, add half a piece of chicken cube and ½ tsp of black pepper (freshly crushed) in it. Mix and fry them for a minute. (Pro tip: Adding chicken cube is optional in the recipe. If you add it, add salt later on after tasting since chicken comes with salt in it. If you are not using chicken cube, add half a teaspoon of salt to the ingredients at this point).
Now, add 3 cups or 750 to 800 ml of water. Also, at this point taste and add salt as needed. Mix everything nicely. Let it cook on a high flame and bring it to a boil. (Pro tip: Do not add a lot of water in the soup. 3 cups or 750 to 800 ml of water is enough to serve 4 people. Do the math).
Then, lower the flame to medium and cook the soup for another 3 to 4 minutes. Check the consistency and boil accordingly. It should not be too runny or too thick.
Finally, add a handful of finely chopped coriander leaves, mix them and cook the soup for another 1 to 2 minutes.
Your homemade tasty and healthy ginger garlic soup is now ready to be served. Transfer it into a soup bowl and enjoy hot.
