You mean TRUFFLE PECORINO? Yes it's expensive, but so is real truffle oil. The cheaper stuff is chemically flavored and contains a hint of real truffle. You might be further ahead to check out D'Artagnon for truffle products. Subscribe to their news letter they have some good sales.
I did with one head, turned out great. I just wanted to know about this cheese because didn't know about it also have 2 bottles of tartufo bianco white and black truffle oil I keep in the fridge. These are years old, you think they are still good? Mostle chilled to solid but warms back to liquid. I have a bunch of asparagus and I was thinking of slicing it up and adding it to the next head I make, you think it would be ok with the cauliflower and cheese?
