Under Italy's baking heat, ice-cold gelato is virtually medicinal. Tartufi (or "truffles" in inglese) are southern Italy's best-loved gelato creation - delicate yet deeply rich ice cream truffles. At the centre, coffee gelato is surrounded by a layer of fior di latte gelato then hand rolled in a light cocoa and almond biscotto crumb.Equally delicious under the warm Italian sun or in cooler climes.
