Example Input: The carbonation in this drink was way too much. So much in fact, that it over powered the flavor. (Orange-tangerine is usually very good together).  I expect this from a soda, but not a "healthy" drink. Lose some of that club soda bite and you have one delicious drink. Until then, I'll pass.
Example Output: 2

Example Input: This mix makes GREAT belgian waffles.  We tried biscuits and pancakes and we do far better form scratch with a standard GF flour.  It does make seriously great waffles though, and we go GF/DF on these.  The waffles freeze extremely well and reheat in the toaster quite nicely.
Example Output: 3

Example Input: Arrived nicely packaged and sealed. An aromatic, lovely tea that I love to blend with others to make custom iced tea blends. I love this Oolong orange with fruity black teas. Recommended!
