Example Input: I love canned sardines and when they put me on a low salt diet I figured that was the end of my sardines until I found these. They taste fantastic,the price is reasonable and you can at least have something that before these sardines was not available to people on a low salt diet. Side benefits as they are skinless and boneless. Thanks to the Roand Co.
Example Output: 5

Example Input: My first time having Curry Rice.  But boy, I cooked this stuff exactly how you're supposed to.  Taste...wasn't bad, I guess, a little "Strong" though.  IT was thick, like ice slush...it was over-bearing and the spice was pretty intense.  I don't think I'll get it again...I guess it's good stuff, seen it in some curry making videos...used often, but...not for me, as it it is way to thick.  I had potatoes, onions, and pork prepared to perfection mixed with it...and I could not taste them, at all. I could not taste the pork, or anything. Only the Sauce.
Example Output: 2

Example Input: I know these are super trendy right now, and I totally wanted to love this product (or, to be more exact, I wanted my toddler to love this product). He took one taste, handed it back to me, and said, "Why you gave me baby food, mom?" I tasted it, and he is right. It tastes just like jarred baby food. Same consistency (not any thicker), too. If your kid likes the packaging, great. If your kid doesn't, then it is just really, really expensive baby food. I'm going to give the rest to my baby, as the toddler is not the least bit interested.
