Example Input: I used this mix to make a 9x13 cake in a glass pan using grapeseed oil, spring water, and free range eggs.  I thought the cake had a nice flavor to it but it was not what I was expecting.  I was craving a white cake (like wedding cake) and went to my local store to find something wheat-free, gluten-free and dairy-free; I purchased this vanilla cake mix.  I think it is a very good mix.  I couldn't really taste the vanilla flavor but thought it had a nice flavor.  The cake is yellow, dense (but not like a pound cake) and texture-y like brown rice has more texture than white rice.  I thought the sweetness was just right.  I think I would purchase again but would make pineapple upside down cake with it.
Example Output: 4

Example Input: We are Chocolate Moose & Mickey Moose,  Our nice owner bought this great food for us.  We love it very much, I have gained 5 lbs. because I eat all of Mickey's food when he isn't looking!  Our skin and fur is much better now too.  :)
Example Output: 5

Example Input: I love these bread mixes. There is nothing like making your own bread. I admit I use a bread maker - not clever enough to use my hands- but I still enjoy the experience. I have tried 2 different Hodgson mixes and they are both excellent.
