Making gelato into big business

20 June 2014 Last updated at 16:58 BST

Best friends Guido Martinetti and Federico Grom decided to go into business together, making gelato.

Guido, a wine maker, and Federico, an economist, had no previous experience in the food industry.

It may not sound like a recipe for success but Italians' love of gelato has meant the two's commitment to quality has paid off.
