Example Input: I really like this granola - their hemp granola is my favorite. REALLY good stuff. However - it's just too sweet for my taste. Most granola is dreadfully sugar-laden, and other than the healthy ingredients, I feel like I'm chomping on some commercial-grade grocery store sugar cereal... -___- That said, the texture is very satisfying and it is tasty. Just a bit sweet. You've been warned.. ;)
Example Output: 3

Example Input: My family is gluten intolerant and we use this product extensively. Pancakes, biscuits, waffles, it doesn't really matter what you need to bake, this mix comes through. This is my go to mix above Bob's and all others we have tried. Try a box, follow the instructions for pancakes, and tell me they aren't awesome... go ahead... I dare you.
Example Output: 4

Example Input: Since I started making Hodgson Wholesome Potato bread, my husband will not eat store bought bread anymore! We make about two loaves a week, in different varieties of the Hodgson Mill brand. The honey whole wheat and white bread mixes are also great. I like using my old bread machine to make the dough, then shape into loaf and bake in the oven. Makes perfect loaf every time, also makes delicious rolls. Glad I discovered this brand of bread mixes on Amazon--they are wholesome, and I know what I'm putting into the bread I bake now. Great product!
