Example Input: I love this coffee. I do wish it came already ground as I don't have a grinder and use a blender instead. But it's worth it. Many flavored coffees I've tried only seem to have a flavored odor that doesn't reach the coffee, but this one manages both.
Example Output: 5

Example Input: Kind of  a ripoff.  I bought the theater box instead of the 5 piece candy bar version and that turned out to be a big mistake.  Each box has only 8 or 9 pieces and they are randomly filled so you are not guaranteed even 1 piece of each flavor.  One box had 6 green pieces and 3 black.  A better value is 20 pack of the original 5 piece bar.  This theater box is sold by weight (4oz) and not volume.  The box is about 90% empty- Ripoff!
Example Output: 1

Example Input: i found this product doing a search for "edible gold leaf." i decided to purchase after reading rave reviews about food items that were created using it. HOWEVER.. it is clearly marked "NOT to be consumed" and "for decorative use only." so this is a misleading product.
