Prior to ordering I misunderstood what truffle oil is... I warmly encourage potential buyers first to google "truffle oil"--you'll discover that there's no such thing. The "truffle essence" put in this and other truffle oils is a synthetic ingredient, whipped up in a lab, that mimics just one flavor of truffles. The aftertaste this (and any truffle oil) leaves is chemical. In order to make it work in a dish, you'll have cover it with garlic and other seasonings: basically, hide the flavor.  There are some oils available through Amazon in which actual truffles are infused, but the problem is that oil doesn't easily absorb real truffle essence, so the presence of authentic truffle flavor is very weak and nearly undetectable.  If you like this artificial flavor, then the price is right ($). But if you want real truffle flavor, get the real thing ($$$).

Had I known this cocoa was sugar-free, I would not have purchased it. I realize that this will not bother some people, but I really don't like the aftertaste of fake sugar.  In the interest of fairness, this did not seem to trouble my nephew!  Just update the description.
The description does not mention that it is sugar-free

'On July 26, 2012 I ordered Lowrey's Hot and Spicy Pork Rinds. I received the Orginal Pork Rinds. I am not happy with this product. I will keep them as they will be to expensive to send them back. I feel you should have checked my previous orders I had ordered, or at least contacted me about my order. Thank you, Colleen Avey
