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.
Origin
According to oral history, the grocer "Daatje de Koe" made the first Vlaardingse iron cookies. Afterwards, the product was introduced in the assortment of various city bakers.Research of the Vlaardingen baker Hazenberg in regional archives showed that the cookie is probably older and dates from the 18th century.
Because of the composition of the dough, the cookies remain tasty for a long time. This made them popular amongst fishermen. These cookies also have a high food energy value, and have been taken to the sea for that reason, too.
Today, most pastry shops in Vlaardingen sell ijzerkoekjes. Also, special waffle irons are available as well as ijzerkoekje flour for baking the cookies at home.
