Truffle flavoring. I love fresh Italian white truffles in the fall, particularly freshly shaved over a simple pasta or risotto. I love fresh black truffles in France.
There is now truffle flavor in far too many dishes. I say "flavor" as I understand that the commercial truffle flavor used in restaurants is often created in a laboratory and not sniffed out by pigs.
Local diners feature truffle fries, truffle burgers, truffle cheese, truffle flavored pasta, salt, honey, etc.
