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 ordered the spotted dick. After eating I felt a little strange. I went to the bathroom and to my horror realized that I had this horrible disease. Luckily 1 gallon 128 Floz Tuscan Whole Milk cleared this up for me.
Example Output: 1

Example Input: Christmas Eve tea (which does not actually contain tea) is not just for Christmas Eve. (Although if you are frazzled, it does releave the stress.) Christmas Eve is good any time. I do not know anyone who doesn't like it, and have often given it as gifts. It is especially nice in the winter when mint teas are a little too brisk and do not produce the same level of cozy comfort as Christmas Eve which is a soothing combination of spices and mint. It is almost as comforting as a cup of warm milk, but without the calories.
