Example Input: Stonewall Kitchen Farmhouse Pancake and Waffle Mix is definitely a mouthful in name but, in taste, not so much. Don't get me wrong, it's not bad but, you could find any number of "mixes" that taste just as well and some even better. I know my taste buds aren't the same as yours so, what's just decent to me may be great to you. I also wish I had bought just one can instead of 2 huge 33 ounce cans. I finished the first can, I'll give the other can away and, I'll continue trying other mixes until I find the "best mix" out there. So far I seem to only be satisfied with a homemade mix for my waffles. My preference is for waffles over pancakes but, this didn't make it on either count. I even tried adding things to it but it didn't really help. Maybe it's just me. Try it if you like but remember, buy only one can just in case you're like me. You can always buy more.

Example Input: We bought these chips at a little sandwich shop in Sonoma while we were on vacation. I wasn't sure what to expect by the package, and at first bite I didn't know what to think...and then all of the flavors hit! Yum! They are a bit spicy, but nothing overpowering. Just lots of crunchy, sweet, spicy goodness. They aren't sold everywhere though, I'm still trying to find them somewhere close to where I live.
Example Output: 5

Example Input: The Chocolate Mocha flavor of this Hot Cocoa is really nice. It's different from the usual Hot Cocoa since it has a hint of Coffee. The quality is definitely there, I find it to be better then the Godiva brand. Mixes extremely easily, there is no residue and works with milk or even water mixed with half and half. I must say that it is a bit much of the same flavor, I would have rather 4 different flavors since the containers are big. Worth it though! A++
