Rev up your taste buds with a shopping spree at Antonio Mattei, Prato's famed biscottificio where the city's signature biscotti di Prato (twice-baked almond biscuits) have been made since 1858. To see the ovens in action, visit in the morning and eat the biscuits (€16.50 per kg) – not sealed, simply wrapped in waxy royal-blue paper and tied with string – within five days.
Note summer hours: the boutique is closed on Sundays from early July to September, plus three weeks in August.
