Example Input: DON'T YOU KNOW THAT SUGAR IS THE SAND OF TIME ?  SINCE THE INGREDIENTS OF KAVLI CRISPY THIN WERE LISTED ON AMAZON, AND THE TIME I RECEIVED MY ORDER,  SUGAR  WAS ADDED TO THIS PRODUCT.  YOU ARE GOING TO GET IN TROUBLE, MISTER.

Example Input: I'm a little perplexed by all the great reviews.  This was the most bland chowder I've ever had.  I prepared it with just milk and a little butter, and it tasted like nothing!  Added some salt and white pepper, still nothing.  Added some black pepper and Provence herbs, now it tastes like herbed potato soup.  On the plus side the clams were nice big chunks and the potatoes were tender.  The consistency was pretty good too.  It just had no flavor.  Not going to be buying this again, certainly not when it's this expensive, too.
Example Output: 2

Example Input: I went to 4 grocery stores looking for this flavor of Jello for my green tomato jam recipe and finally found it here. This jello is wonderful! Evidently it's only carried in the stores during the summer but with harvest time in the Fall, I couldn't find it anywhere in town. This Jello tastes like watermelon and the jam recipe I made with it takes like watermelon jam! Great made as regular Jello too. Yummy!
