Yan su ji is the Taiwanese name for the fried chicken snack commonly translated as salt-and-pepper chicken.
Taiwanese popcorn chicken is made from bite-sized pieces of chicken, commonly marinated with ingredients such as soy sauce, garlic, five-spice powder, and rice wine. The pieces are coated and fried, then often seasoned with pepper, salt, and fried basil leaves.
The Mandarin name 鹽酥雞 is commonly rendered in English as “salt-and-pepper chicken.” Night markets and street-food stalls are strongly associated with the snack, which is usually served in a paper bag or cup.
Yan su ji should not be confused with Taiwanese three-cup chicken, a braised dish, or lu rou fan, a minced-pork rice dish. Those are separate Taiwanese specialties.
