Iron eggs

Iron eggs are a dark, firm braised-egg snack associated with Tamsui in northern Taiwan. Repeated braising makes the eggs smaller, darker and firmer than ordinary braised eggs. New Taipei’s tourism account describes an elastic texture and a concentrated aroma, and places them among the foods sold along Tamsui Old Street.^[1]

The city’s account of A-Po Iron Eggs describes eggs braised with soy sauce and herbal ingredients. It records the business’s establishment in 1980 and names Lu Yang Biyun as its founder. The snack’s origin is told through stories of eggs braised unusually long or returned repeatedly to the pot; these are local accounts of its development rather than a precise recipe shared by every producer.^[1][2]
