Egg Puffs (also called as Gei Dan Jai, Egg Waffles, Eggettes or in Chinese 雞蛋仔) is a Hong Kong style waffle usually made and sold by street hawkers and eaten warm on the street. They are crisp on outside with a little layer of doughy-creamy texture on the inside, but the bubbles are hollow.
Egg, sugar and evaporated milk are used in the Egg Puffs recipes, giving them a sweet flavor. They are generally soft and not dense. Traditional Egg Puffs are full of the flavor of yolk. Sometimes different flavors, such as chocolate and honey melon flavor are used in the recipe and create various colors.
The batter is very thin and poured from the pitcher into Egg Puffs iron which is a two piece mold that is then closed and flipped around to distribute the batter.
The bags have little holes in them so as to prevent condensation from the heat.
