Speculoos is a type of shortcrust biscuit, traditionally baked for consumption on or just before St Nicholas’ feast (December 6th) in the Belgium, the Netherlands and Northern France. In recent decades it has become available all year round.
Speculoos are thin, very crunchy, slightly browned and, most significantly, have some image or figure (often from the traditional stories about St. Nicholas) stamped on the front side before baking; the back is flat.
The Lotus brand is one of the most popular. You can also find them covered in chocolate…a real Belgian treat!
