What is a Truffle? Edible
mushrooms are either Saprobes which grow on dead matter, Parasites which grow on living plants or - as is the case with
truffles - Mycorrhizal which establish a symbiotic relationship with the roots of suitable host trees. Varieties include the Perigord
Black Truffle (tuber melanosporum), the Burgundy Truffle (tuber uncinatum/aestivum) and the Cep or Porcini mushroom
(boletus edulis).
In 2008/9, the average price in European markets, per kilo, was:
Black Truffle £900
Burgundy Truffle £290 White Truffle £2800
Where do they grow?
Truffles can be found throughout the world but are most revered in southern Europe, particularly France and Italy.
Suitable
growing areas in Great Britain are likely to be over chalk or limestone ie: Chiltern Hills; North and South Downs. Between
Norwich and Cambridge; Hampshire and Wiltshire into Dorset, between Hull and Lincoln; north of Oxford; south to Gloucester; east
to Bristol; the south coast west of Portland; West Devon around Brixham; west of York to Nottingham and parts of the Peak District.
This is because truffle cultivation requires soil with a high pH (in excess of 7.3 for Burgundy truffle and 7.9 for Perigord Black
truffle). Recent recorded 'finds' stretch as far north as Darlington in Yorkshire.
How do you harvest truffles?
Traditionally, pigs have been trained to find truffles but dogs are increasingly used these days. Truffle UK Ltd is able to
provide dog training. Another intriguing method of finding the truffles is to observe where the truffle fly - la mouche - lays
its eggs; it is believed that they choose only the finest truffle in which to do this.
