These biscuits originated from the city of Vlaardingen in South Holland. Made by a Dutch grocer named Daatje de Koe around 1838, they have become a basic staple biscuit for bakers. The ijzerkoekjes used to be popular with fishermen because of their high nutrional value and could be kept for a long time without spoiling. The iron baking plate pattern gives the biscuit its distinctive look. You could cook these in a cast-iron pan or a hot plate.
