Example Input: This was a weird drink - I had high expectations, but the flavor was just odd - it really did taste like fizzy Tang drink mix.  However, my kids really liked it, and I think it is a great alternative to junky soda, so I will most likely buy more - but not for ME to drink.  ;)
Example Output: 3

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: I was diappointed in the flavor and texture of this mix.  I usually like most of the Low Carb things I have tried, but was diappointed in this specific one.
