Example Input: These chips taste awesome. And unlike most other flavored chips, they actually make sure that plenty of the flavory salty goodness gets on each individual chip. Just don't pass gas near any pretty ladies after consumption. They'll totally know it was you.
Example Output: 5

Example Input: This stuff is pretty solid. Makes a decent enough pancake for being GF and makes a solid biscuit as well. What we have found works best is taking this mix and using it half and half with the Chebe mix. Between the two it makes for a very nice flour mix. The Chebe is good but on its own tends to be a little squishy, but when you mix it with the bisquick, the bit of squishiness gives the dryer Bisquick the fluffiness and moistness it needs. So, I recommend this, but I would HIGHLY recommend getting some Chebe too and cutting the Bisquick with it. Also, even though this mix has leavening agents in it, when we use recipes that call for leavening agents we add them anyway, it tends to turn out better this way.
Example Output: 4

Example Input: I have not eaten this popcorn or tasted it myself, it was part of a gift for my daughter in Grad School.  She likes the fluffy quality of the popped corn and the not so many hulls - also the big bag makes her think she can make it last until Christmas ( that remains to be seen) without having to buy more.  A very good snack for a poor Grad Student
