Jodenkoek

A jodenkoek is a big, flat, round shortbread biscuit with a diameter of about 10 centimeters (4"). Claimed to have been first baked in the 17th century, these biscuits were advertised by bakeries as early as 1872. Jodenkoeken were made famous by a baker called Davelaar, in Alkmaar, the Netherlands. The Stam bakery in Alkmaar started selling jodenkoeken in 1883, and Gijs Verhoeven took over this bakery in 1924. By advertising in local newspapers and by offering the biscuits through other shops, his jodenkoeken became a popular product. The company continues to bake them to this day. Similar products with the same name are produced by Lotus Bakeries and O'Lacy. Some producers still use the old spelling, jodekoek, while others have changed the name of the product to jodenkoek, after the new orthography of the Netherlands from 1996.
