Example Input: Always wanted to make my own hummus and eggplant dip - this brand of tahini I'd never tried before or seen in supermarkets, so I decided to order and try it....excellent by itself or in recipes! Highly recommended.
Example Output: 5

Example Input: My wife and I tried this product a few days ago. We were not disappointed. The coffee had a good flavor, and the low acid was a nice added benefit.
Example Output: 5

Example Input: I agree with the company motto "A Natural Obsession". I tried a small bag at the local store and immediately bought in bulk online to save about 30 percent. The flavor of these is very strong, so they are best paired with a food that has a very mild flavor, like steamed vegetables or plain whole grain bread. Otherwise they compete or clash with the other food.
Example Output:
