Directions
Take a large mixing bowl, add the cornstarch, lemongrass, sugar, pepper, fish sauce, 1 tablespoon of the vegetable oil, and the cubed chicken. Mix well till the pieces are well-coated. Set it aside for 3-4 hours. When you are ready to cook, take a separate vessel and pour the remaining 3 tablespoons of oil in it. Heat the vessel, then add the shallots and garlic to it. Fry till they are light brown in color.
