How to Make It
In a small bowl, combine the sugar, fish sauce, water, rice vinegar, garlic, ginger, pepper and chiles.
Heat the oil in a large deep skillet. Add the shallot and cook over moderate heat until softened, about 4 minutes. Add the fish sauce mixture and the chicken and simmer over high heat until the chicken is cooked through, about 10 minutes. Transfer to a serving bowl, garnish with the cilantro and serve.
Because fish sauces vary in their saltiness, Phan advises adding the fish sauce to taste.
