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: We received a gift box that contained the Stonewall Farms Pancake Mix and they were out of this world. They are the lightest, fluffy and flavorful pancakes and waffles you will ever taste. And the price on Amazon is a big savings over ordering from Stonewall Farms. Don't shy away from the larger size and the two pack because you will devour these pancakes in no time.
Example Output: 5

Example Input: Finally a gluten free mix that tastes great! I have used this mix over and over and I have never been disappointed. It works just the way the regular mix works and it has opened up a whole new world for me. I thought I would never be able to find a mix that I like, but this one I love. I am excited about trying all the fun things I can do with it. Even cookies!
