Example Input: Not quiet what I was expecting. The cherries were dried and could not taste the brandy. The dark chocolate was good but too crunchy.
Example Output: 3

Example Input: Several of the seller's listings indicate 20% Kona blend.....but the delivered product does NOT have this package printing. As a long-time Kona coffee drinker, the contents are more indicative of 10% (or less) Kona coffee. Have ordered twice....and completely disappointed.
Example Output: 2

Example Input: Just had my 1st can of these sardines and I am delighted! Big sardines in the can with a most excellent mild flavor. Made a tuna salad...but used sardines. Wonderful! I have to say that I really didn't notice that they were low sodium as far as affecting the overall sardine taste. Love the ones without oil as I don't really like that greasy fish taste you get with some sardines. I just got diagnosed with hypothyroidism, and I read that sardines are good to help restore your thryoid function. I'll be ordering more of these!
