When you notice the aroma releasing from the mixture, remove ginger, garlic, coriander, and lemon grass bunch from it. Add mushrooms, chilies, baby corn, and salt to the mixture. Allow it to simmer for about 15 minutes in the covered pan. When the broth becomes thick, add lemon juice, just before serving. Garnish it with carrot, coriander, and spring onion. Serve it hot with cheese-flavored breadsticks.
