Perfume makers should give up on chasing pheromones and start trying to mimic the scent of truffles instead, the aroma is so irresistible.

Have you ever used truffle oil in your cooking? I think I have a new best friend in the kitchen. I don't want roasted potatoes any other way than tossed with a bit of truffle oil.

Yes it is expensive, $12 or more for a little 3 ounce bottle. (Found my bottle at Whole Foods.) But you don't need much; the amount of truffle oil required for this recipe will cost you anywhere from 25 to 50 cents. Small price to pay to see everyone's eyes light up with delight as they take their first bite.

Truffle oil is especially good with potatoes as the starchy potatoes just soak up the truffle flavor from the oil. These are just basic roasted new potatoes and onions, easy to make, hard to mess up, but they taste out of this world with a few drops of truffle oil.
