Prepare the momos by following my tutorial and keep them aside.
To make the broth, put the chicken stock, sliced ginger, soy sauce and brown sugar in a pot and bring to a boil.
In the meantime, cook the momos in hot boiling water for 3 or 4 minutes, or until cooked through. When they are ready, drain them and divide them into 4 serving bowls.
Cover the momos with the hot broth and garnish with sliced green onions, chopped coriander leaves and sliced red chilli.
