The invention of this dish is often attributed to Frédéric Krieger, also known as "Monsieur Fritz"; a German pioneer of chip stalls. He allegedly served mussels and fries for the first time in 1875, at the fairgrounds in Liège. Today, this popular recipe is emblematic of the cuisine of northern France and Belgium. It is even the specialty of the Braderie de Lille, where merchants compete to create the highest pile of shells!
