Gris de Lille (also known as Puant de Lille, Vieux Lille, and Puant Macere) is an extremely pungent French cheese produced in the region of Nord-Pas-de-Calais. The cheese is made with cow's milk, and it is washed in brine for three months.
Its texture is semi-soft and slightly elastic, while the flavor is salty and strong. The cheese is produced in square blocks, and the northern miners used to enjoy it while working down in the pit. It is recommended to serve this unique cheese with a glass of strong beer or a cup of black coffee on the side.
