Mimolette is a cheese traditionally produced around the city of Lille, France. In France, it is also known as Boule de Lille after its city of origin, or vieux Hollande for being made after the tradition of Edam cheese from the Dutch province of Holland. In some areas of Belgium and the Netherlands, such as Flanders, it is also known as commissiekaas.
A cow's-milk cheese, it normally weighs about 2 kg (approximately 4.5 pounds). Its name comes from the French word molle, meaning "soft". This refers to the softness of the crust when young - with age it becomes harder. It has a gray crust and orangish flesh. The orange color comes from the natural colorant, annatto. The cheese has a similar appearance, at first glance, to a cantaloupe.
The greyish crust of aged Mimolette is the result of cheese mites intentionally introduced to add flavor by their action on the surface of the cheese.
