Mimolette is a cheese traditionally produced around the city of Lille, France (where it is also known as Boule de Lille), and also in some areas of Belgium and the Netherlands.

The greyish crust of aged Mimolette is the result of cheese mites intentionally introduced to add flavour by their action on the surface of the cheese.

Mimolette can be consumed at different stages of ageing. When younger, its taste resembles that of Parmesan. Most cheese-lovers appreciate it most when “extra-old” (extra-vieille). At that point, it can become rather hard to chew, and the flesh takes a hazelnut-like flavour.
