People also seem to be split on whether it is real or not. Some are saying it is a hoax and others are saying it is real. If it is real, and I were DOM for that company, I'd be jumping on some of the blogs and letting people know. I'm not seeing that, so I'm guessing it is fake. Or they have a really bad DOM.

What about the burnt powder? Does my duck taste a la range or a la cordite?

I don't think I will be trying those anytime soon.
