Scorch-frying

Stir-frying materials in a wok over a high flame until they become burnt on the outside and emit a burnt smell. Abductive dispersing medicinals such as medicated leaven (Massa Medicata Fermentata, 神曲 shén qū) and crataegus (Crataegi Fructus, 山楂 shān zhā) are scorch-fried to strengthen their spleen-fortifying food-dispersing action.
