A food of convenience, calzoni are the last word in edible portability. In essence a type of Italian street food, these “bread pasties” have become increasingly popular in the UK and beyond. It’s a rather intriguing – though welcome – development that both local and national pizzerias and Italian restaurants have begun offering calzoni alongside their usual fare. After all, a calzone is probably best suited to the busy lunch hour, dispensed by a market vendor to the satisfaction of all. Still, I hope you’ll agree that once open and spilling forth, the contents of my Sweet Potato and Mozzarella Calzone are really rather appetising.
