Example Input: Very crisp and tough, does not melt, but  breaks down into pretty large particles in your mouth.  I enjoy it as a cereal, but neither of my 11 mo old twins really enjoy the tough texture.  They like the melt in your mouth and less sugary taste of the happy baby <a href="http://www.amazon.com/gp/product/B001NXHY8Y">HAPPYBABY Organic Puffs, Banana Puffs, 2.1-Ounce Packages (Pack of 6)</a> or <a href="http://www.amazon.com/gp/product/B001NXM3I0">HAPPYBABY Organic Puffs, Greens Puffs, 2.1-Ounce Packages (Pack of 6)</a> which is almost salty. They also love saltine or ritz crackers Annies brand and those saltines are just as hard to chew and great for teething on.

Example Input: Ingredient list: Sugar, Acidity Regulator (including miscellaneous chemicals). No tea whatsoever. $22 for 18 oz. (500g) of sugar with apple flavor. Most expensive sugar in the market!! Health benefit? None! It comes in a square tin with plastic bag inside containing granulated sugar. That's all. Nothing more.
Example Output: 1

Example Input: I subscribed to these - one case every three months. That comes out to about $5 a month for the convenience of having my favorite chips handy whenever I want. Because it seems Frito-Lay has managed to crowd out every other chip vendor from pretty much all my local stores this is the best way to ensure a steady supply of the items I want rather than the items Frito-Lay wants me to have. The two ounce bags are larger than you might be used to buying at the Subway (for example) which I find works very well - they're large enough to be a good snack on their own, or you can even share a single bag over lunch. The size is perfect for ensuring these fantastically crunchy chips are always fresh - no chip clip needed!  The only problem? I subscribed to four cases a year and having these yummy chips always in the pantry makes it really easy to increase ones Kettle chip consumption. Definitely have to hide the case from the kids!
