Guangzhou's egg tarts are a masterpiece of texture. Two styles exist: the puff pastry version (with hundreds of paper-thin, buttery layers that shatter on contact) and the shortcrust version (more cookie-like, sturdy). Both are filled with a wobbly, silky egg custard made from eggs, sugar, milk, and vanilla. The best ones are served warm from the oven, the custard still trembling, the pastry still warm and fragrant. They're a dim sum staple and an afternoon tea favorite.
Egg tarts arrived in Guangzhou through Macau's Portuguese influence in the 20th century. Cantonese bakers adapted the recipe, creating the lighter, less sweet version that became the city's standard.
