The Canterbury Truffle Festival is back next weekend, with truffle hunts and lots of chances to taste the winter delicacy.
Organiser Gareth Renowden said the annual festival was New Zealand's only celebration of ''the prestigious and expensive underground fungi'' and runs from July 14 to 29.
''Truffles are the underground fruiting bodies of fungi that grow in lime-rich soils in association with trees such as hazels, oaks and pines,'' he said.
''They develop amazingly powerful aromas and flavours and are a celebrated and revered part of the cuisine and food cultures of France and Italy.''
New Zealand's black and white truffles could command more than $3000 per kilogram, he said.
