These biscuits, with their bright blue bags, can be bought directly from their producer in Prato.

Mattei cookies are also called Mattonella.

The origin of this name, for which the shop has become famous, is unknown. It may possibly be a hint about the consistency of the biscuit itself! However the most probable explanation is that it refers to the shop’s 1920’s brick façade. Passers by, noticing the exotic mattonelle (bricks), referred to the bakery and its products by this name.
