Example Input: These potato chips are DELICIOUS! I have not had potato chips in approximately two years as it has been difficult to find organic chips. Amazon lowered the price on these, and I finally had a chance to order them. I most definitely will be ordering them again! My family and I love them. They are pure and void of all artificial flavorings. The true flavor is present, and it satisifies the need for something salty, sweet, spicy, and crunchy. A++++
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: If I had to describe a Popchip, I would say that it's a hybrid of a potato chip and a popcorn cake. I was a little skeptical, at first, since I was trying to figure out how they were made if they weren't baked or fried, but I was pleasantly surprised when I tried them. This variety pack gives people a good opportunity to try the six different flavors and decide which ones are their favorite(s). If you're a snacker or if you are looking for a healthier alternative to fried potato chips, this are a must-try.
