Example Input: This is a great product, we have made custard with it for years and it always makes great custard. We will purchase this product again. Amazon does a great job of getting us our purchases fast and without damage.
Example Output: 5

Example Input: This is a very different sauce - nothing like anything you'll find in the grocery store. It's closer to the "botique" salsas that have recently appeared with the new "taco restaurant" trend. It's a little smokey. My picky 3-year old will eat a burrito with this on it. My family always had this (mild) on the table in Southern California and now that I've been transplanted in South Florida I am happy to mail-order. You can get the little single-serve pouches directly from the company, too.
Example Output: 5

Example Input: These pancakes just hit the spot and make me feel like I am eating a restaurant breakfast at home for a lot less money. Splurge on this and the good maple syrup...it really is cheaper than going to Denny's or IHOP where a meal for two will be $20 minimum.
