Ijzerkoekje

An ijzerkoekje is a soft cookie, traditionally eaten by Dutch fishermen, especially in Vlaardingen, one of the main harbours of the Netherlands during the 19th and 20th centuries. It is an oval cookie around 0.6-0.7 cm thick with a cinnamon 'creamy' taste. The cookies were invented in the city of Vlaardingen and are baked on a checkered iron plate, creating a characteristic waffle-like pattern, similar to stroopwafels.
