Yeah...our bottle is about $35.

It's an Italian brand called Terrabianca, Olio aromatico al tartufo and it actually has a little truffle segment sitting at the bottom of the bottle. I've tried a few truffle oils as this is the best by far. In Perth, it's stocked at Simon Johnson and Mondos (gourmet butcher) though it might also be elsewhere...

When I was in Sydney, we bought it at Peters at Kensington...

As has been mentioned, you only use the tiniest bit as it is pretty potent...A bottle should last 6 months...even if you are using it pretty regularly.

It is gorgeously delicious...wonderful as a tiny little drizzle over pasta, a little over a roast...mmmm...going to have some tonight!

We went to the wine and truffle farm in Manjimup (South West WA) recently. They grow their truffles which are worth huge amounts/kilo (but they are also incredibly difficult to grow).

Yum!
