Truffles are forever

The world’s most expensive fungi, these “black diamonds” are found by specially trained dogs and pigs in the roots of certain trees. Cheaper alternatives to fresh truffle (though still a little pricey) include truffle oil and truffle salt. You may find fresh, frozen and preserved truffles, truffle oil, truffle butter and truffle salt through gourmet food shops.

Once you have found your truffles you must master the art of cooking it -or to be more accurate, not cooking it: Truffle has a very intense, earthy flavour, so only a little is needed. Very thinly shaved truffle is magnificent on top of a simple pasta dish. Avoid cooking with fresh truffle or truffle products – instead use them to flavour dishes just before serving.
