Example Input: I really like the frozen Corn Muffin Tops, but the mix resulted in a dryer product. I used the paper muffin liners and I think these might have added to the dryness.
Example Output: 3

Example Input: I was looking forward to this tea, but unfortunately the mint overpowers the hibiscus and essentially makes this just another kind of mint tea.  I prefer the hibiscus tart be the star of the show in a hibiscus-based tea (aka "herbal infusion") and in my opinion, mint and "tropical" don't mix and now know going forward to pay more attention to the ingredients.  Still worth 3 stars because it can be a refreshing tea on a hot day, but just not a great tropical/hibiscus tea.
Example Output: 3

Example Input: I got these anchovies as a gift for my anchovy-loving boyfriend. While he liked them well enough, they were just too salty to be able to even consider getting through the entire can, even over months. We soaked them in water prior to consumption and that helped, but on the whole I think they would have been more enjoyable with about 1/16th of the salt.
Example Output:
