A sweetheart cake or wife cake or marriage pie is a traditional Chinese cake with a thin crust of flaky pastry, made with a filling of winter melon, almond paste, and sesame, and spiced with five spice powder.[1]
"Wife cake" is the translation of 老婆饼 from Chinese, and although the meaning is "wife", the literal translation is "old lady cake", paralleling the colloquial usage of "old lady" for "wife" in English. In Hong Kong, it is known as a specialty of the Yuen Long District.[2]
