With the pot-in-pot method, it’s easy to make this tasty ginger and garlicky treat of chicken breasts rolled around scallions and lacquered in a sweet-and-salty sauce. To create the rolls, the recipe requires chicken cutlets, not just boneless skinless chicken breasts. You can sometimes find the cutlets in the meat case at the supermarket.
You can also DIY it by putting a chicken breast between two sheets of plastic wrap, then flattening the chicken with the smooth side of a meat mallet or the bottom of a heavy saucepan. Give it forceful, straight downstrokes so that the meat doesn’t thin out at its edges.
(And repeat with three more breasts and clean sheets of plastic wrap each time.) Or you can ask the butcher at your supermarket to do the job for you. (Tip well!)
