Actually Mattei bakery doesn't produce only cantuccini. Here, you can also find many traditional cakes like the Mantovana (or white cake). It's said that the original recipe of the Mantovana dates from the 19th century, when Antonio Mattei received it as a gift from two nuns from Mantua to thank him for his hospitality.
After Mattei, the factory has been managed by three generations of the Pandolfini family, the descendants of the best Mattei apprentice and foster son. Today, you can find biscotti di Prato in this and other shops, in Prato and around the world and at many Tuscan tables with a small glass of Tuscan straw wine or Vinsanto. Anyway our advice is to venture out to explore the city of Prato, to get lost in its narrow streets to better savour the sweet taste of this story.
