Example Input: there is a taste of sugar substitute, the aftertaste turns me off, I've even tried using a little bit of milk in the mug before hand to hide the taste. It didn't, so i'm just using Swiss miss powder and a little milk to make it a creamier hot chocolate before using using my keurig.
Example Output: 2

Example Input: I am glad I found this on the reduced rack for 99c. The taste was not bad but no way I could frost my cake. It stuck to the knife,ran down in strings,what a mess. I too thought I had gotten a bad batch.My GDs birthday cake looks like crap. Who would buy this mess. Horrible
Example Output: 1

Example Input: These are actually pretty good little potato puffs, and best of all - no CHEESE! (unless you like that sort of thing, which we don't so it's nice to actually find a potato side dish with no cheese in it). Anyways- - these are surprisingly good and they toast up nicely in the oven in like 10 minutes. worth it for $10.
Example Output:
