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 Input: When I first found out that my 4 year old I had to go Gluten free I was a little worried about how she would handle it. GF Bisquick has made it a lot easier. I have been able to make her favorite foods such as chicken fingers, corn dogs, pizza and chinese (sweet and sour chicken)with this mix. Pancakes are also a big hit in our house. They have quick and easy recipes on the box. For the chinese- I take their chicken finger recipe and cute the pieces of chicken into bite size pieces, and bake according to the recipe. Cook up some rice and just use a GF sweet and sour sauce a quick simple easy meal that tastes wonderful!

Example Input: The flavor of Big Train Hazelnut is not significant. One has to add a lot to have a flavor impact. Of the three Big Train flavors I purchased (including Vanilla and Irish Creme), Hazelnut is the least satisfactory. (Vanilla's a little better; Irish Creme is best--I gave that one 4 stars).
