What it is

Iron eggs are a Taiwanese version of soy-braised eggs, shrunk and toughened by repeated stewing and drying. They are dark brown, chewy, and taste sweet, salty and a little spicy. Chicken, pigeon and quail eggs are used, and quail is the most popular.

Where it comes from

They come from Tamsui in New Taipei. Yang Bi-yun, who opened the first iron egg shop there in 1980, said she invented them by accident by reheating unsold soy eggs again and again. A competing local story credits a noodle-stall owner, Huang Chang-nian, in the 1970s.

How it is made

Eggs are stewed in a spiced soy broth, then air-dried, and the cycle is repeated until they shrink and darken.

How to eat it

Snack on them with a drink, or put one beside a rice dish.

In Kaohsiung

At Bei Gang Tsai in Kaohsiung's Yancheng district, Michelin suggests a soy-marinated iron egg with the tube-steamed sticky rice.
