question:
Google "propylene glycol" to find out why.  I bought this product, along with several others, without running the ingredients by my wife first (a nurse of 30 years) she was surprised when she noticed it.. we went a googling, and poured my $50 order down the drain afterwards.  There's "pure" and then there's "not so much".....  from the website:  [...]  Propylene Glycol  A cosmetic form of mineral oil found in automatic brake and hydraulic fluid and industrial antifreeze. In the skin and hair, propylene glycol works as a humescent, which causes retention of moisture content of skin or cosmetic products by preventing the escape of moisture or water. The Material Safety Data Sheet warns users to avoid skin contact with propylene glycol as this strong skin irritant can cause liver abnormalities and kidney damage. Also used in:    Tyre sealant   Rubber cleaner   De-icer   Stain removers   Fabric softener   Degreaser   Paint   Adhesive   Wallpaper stripper  I wrote the company about this concern and they never responded....

question:
We bought these chips at a little sandwich shop in Sonoma while we were on vacation. I wasn't sure what to expect by the package, and at first bite I didn't know what to think...and then all of the flavors hit! Yum! They are a bit spicy, but nothing overpowering. Just lots of crunchy, sweet, spicy goodness. They aren't sold everywhere though, I'm still trying to find them somewhere close to where I live.

question:
Just got this order and it is ok. A bit light on the cheddar flavoring and herb taste eludes me, if it is there.
