Where it comes from
Usually traced to Guangzhou in the early twentieth century, in the tea rooms of department stores, perhaps after the British custard tart; it became a fixture of Hong Kong bakeries and cha chaan teng. Macau's version, with a blistered, scorched top, is later and closer to the Portuguese pastel de nata.
