This tea has NO flavor, tastes like dust It "looks" like quality -- pretty package -- but it's no good. Lipton regular Pekoe is farrr superior.

Ex Input:
I discovered these when I moved to Canada a few years back.  Before this I had only experienced a thicker Wasa crispbread and was a bit put off at first.  The feelings dissolved the first time I ate one of these with light laughing cow cheese.  They are a little more "powdery" than I'd like, but they compliment most cheeses very well without overwhelming them.

Ex Output:

Ex Input:
I bought these cookies after reading all the rave reviews but they were very dry, didn't have much chocolate, and left an unpleasant aftertaste. I don't understand what all the fuss is about. If these were the only GF cookies available, I still wouldn't buy them again.
