Paccheri is large hollow tube-shaped pasta. The Paccheri pasta shape is similar to rigatoni, but Paccheri is shorter and have a larger diameter. Legend has it that the Paccheri shape was invented as a way to smuggle at least 4 garlic cloves in each piece. Italian garlic farmers thought that the garlic in what once was Prussia and is now Austria was less flavorful than that grown in Italy. when the Prussian government banned trade in Italian garlic, the Italian garlic farmers hid garlic cloves inside Paccheri pasta when crossing the border.
