Iron egg

The dish consists of small eggs that have been repeatedly stewed in a mix of spices and air-dried.

It has been said to taste "sweet, spicy and slightly salty with a concentrated egg flavour—a great snack with drinks".

[1] Iron eggs were popularized by shopkeeper Yang Bi-yun (楊碧雲), who opened the first store selling the product in Tamsui in 1980.

The recooking and drying process eventually resulted in shrunken eggs that were dark, flavourful, and chewy, which were extremely popular with the locals.

[5] The popularity of iron eggs has risen and they can be found in other regions besides Taiwan, such as in Africa and the Middle East.
