Example Input: I love Cherrybrook Kitchen and have tried almost all of their products.  I was excited to try the Ready to Spread frosting, as I do not usually keep the needed ingredients on hand for their box frosting.  I am not a picky eater, especially if the item contains sugar... but this was horrible!  The consistency is absolutely nothing like regular canned frosting.  It is not light and fluffy.  It is very gooey.  I cannot even imagine trying to spread it on a cake - it would rip it to pieces because it is so thick and gooey.  I did not even try it on a cake, because the taste and texture were so off-putting.  Seriously, do not waste your money!
Example Output: 1

Example Input: A few years ago, going Gluten Free was really difficult. I missed the basic things I loved to eat and pancakes were certainly one of them. I tried other mixes but the batters were very dry and required items to moisten them such as fruit, etc. But Bisquick's GF pancake mix was surprisingly good! It is a great alternative to the real thing. Certainly all of us Gluten Sensitives out there know it will never be that delicious stack of buttermilk pancakes like we once knew, but I'm happy to know there's a great alternative. :)
