Example Input: Halloween is over but, I sent a bag to my daughters class for her share. The chocolate was fresh and enjoyed by many.
Example Output: 5

Example Input: This mix allowed my little one to have cupcakes at his second birthday party.  They turned out great and with some homemade vanilla icing, they were a hit with everyone!  I even used Ener G's egg replacer to replace the multiple eggs the mix calls for.  One hint, bake for almost the maximum time on the directions.  They come out golden brown and moist.
Example Output: 5

Example Input: I bought these and tried each flavor. I could not even finish any bag but the barbecue. I really liked the barbecue but all the other flavors were gross. And the texture is really like fingernails on a chalk board to me. HOw is this the #1 best-selling item? Amazed. Anywho to each his own! Godbless and enjoy. But if you are like me and enjoy barbecue just get the barbecue kind!
