Chinese Preserved Duck (Lap Ap / 腊鸭)

Overview

Air-dried preserved duck — salt-cured, flavoured with soy, five-spice, and sugar, then hung to dry in cool dry winter air for 2–4 weeks. A seasonal Cantonese tradition practised from late November through January when cool winds provide ideal drying conditions. Used in clay pot rice, congee, or steamed over rice. Different from Peking Duck — this is a preserved, not freshly roasted, preparation.

Flavour Context

Intensely concentrated duck flavour with soy-spice complexity; the air-drying concentrates proteins and fats dramatically

Key Principles

{"Duck cleaned thoroughly; cavity packed with salt and spices; hung upside down to drain","Cure: soy sauce, dark soy, rose wine (mei gui lu), five-spice, sugar; rub and marinade 24 hours before hanging","Ideal conditions: 5–15°C with good airflow; direct sunlight should be avoided to prevent rancidity","Ready when duck feels firm throughout and darkens to deep mahogany"}

Pro Tips

{"Best lap ap produced in Zhongshan, Guangdong — known as the regional excellence benchmark","Use lap ap to flavour clay pot rice: place on top of raw rice with soy sauce; cook until crust forms on rice bottom","The rendered fat from lap ap adds incredible flavour to vegetables stir-fried in the same wok"}

Common Mistakes

{"Drying in warm or humid conditions — duck putrefies instead of drying","Insufficient salt during initial cure","Not soaking before use — lap ap is intensely salty and needs 30 min water soak before cooking"}
