Egg puffs began to be sold on Hong Kong streets since the 1950s. In those days, charcoal was used as fuel and a heavy metal cast was used to make the snack. In recent years, the cast has become lighter and the vendors have switched to LPG for fuel.

This vendor highlights that he uses no artificial colouring in the egg puffs, which have a light yellow colour. A sharp yellow colour may be an indicator of using artificial colouring.
Egg puffs began to be sold on Hong Kong streets since the 1950s. Grocers, out of an intention not to waste things, made the snack by mixing cracked eggs with flour and butter and toasting the batter in a cast.
With a new cast design, the snack then took a ball shape, that became the very popluar egg puffs we know today. At the beginning, duck eggs were used for its stronger flavour.
Egg puffs have all along been sold on wheelbarrows. But in recent years more and more snack shops have started to serve them. They now come in different flavours, such as chocloate, coconut, and black sesame.
