The egg tart started being sold in the early 20th century in
Guangzhou (Canton), Guangdong province, inspired by the English custard
tart. Guangzhou's status as the only port accessible to foreign traders
led to the development of Cantonese cuisine having many outside
influences. As Guangzhou's economy grew from trade and interaction with
Britain, pastry chefs at the Western-style department stores in the city
were asked to invent new pastries weekly to attract customers from
competitors.
The egg tart, featuring a lard-based puff
pastry crust and a filling similar to steamed egg pudding, was invented
by a department store for one of these "Weekly Special" competitions.
The Zhen Guang Restaurant in Guangzhou is also credited with inventing
the Chinese egg tart.
The outer shell may be made with shortcrust pastry or puff pastry.
