Tender poached chicken is chilled briefly, shredded, and finished with a hot scallion ginger soy sauce that soaks into every bite. This simple Chinese-style chicken dish is light, savory, aromatic, and excellent with steamed rice or crisp cucumbers.
Place 4 cups water in a medium pot with the ginger slices and 1 scallion. Bring to a boil, then lower in the chicken drumsticks. Return the water to a gentle boil, reduce the heat to low, cover, and simmer for 10 minutes; the water should move lightly without a rolling boil.
Turn off the heat and keep the pot covered. Let the chicken sit in the hot poaching liquid for 15 minutes, or until the thickest part reaches 165°F and the juices run clear.
Transfer the chicken to a bowl of ice water and let it chill for 5 minutes to stop the cooking and firm the meat. Drain well, remove the meat from the bones, and shred it onto a serving plate.
Separate the remaining scallions into white and green parts. Thinly slice the whites and chop the greens. Heat the vegetable oil in a small saucepan over medium-low heat, then cook the scallion whites until lightly golden and crisp. Spoon the scallion whites over the shredded chicken.
Add the light soy sauce, sugar, and 1/2 cup of the chicken poaching liquid to the oil left in the pan. Bring to a boil, stir in the chopped scallion greens, and taste for seasoning. Pour the hot sauce evenly over the chicken and serve warm or at room temperature.
For boneless, skinless chicken breast, simmer for 5 minutes, then let it stand covered in the hot liquid for 15 minutes before checking doneness. Keep the poaching liquid gentle so the chicken stays tender. Leftovers can be refrigerated in an airtight container for up to 3 days; spoon extra sauce over the meat before serving.
