I bought a small bottle of truffle oil a few years back. a drop in a pot of pasta is a different flavour, kinda of earthy, sweet, tough to describe.
Put in three or four drops, might as well chuck the pot of pasta cuz the flavour is very strong.
Never had fresh truffle though, just the oil. Wife doesnt like it at all but she doesnt like scotch either so obviously her palate is not as refined as mine
