Example Input: I love this product! It is the best natural sweetener I have ever tried, and I have tried many. You can use also as pancake syrup or as a substitute for honey on your peanut butter and honey sandwich. It last a long time, and is a good value.
Example Output: 5

Example Input: This stuff is pretty solid. Makes a decent enough pancake for being GF and makes a solid biscuit as well. What we have found works best is taking this mix and using it half and half with the Chebe mix. Between the two it makes for a very nice flour mix. The Chebe is good but on its own tends to be a little squishy, but when you mix it with the bisquick, the bit of squishiness gives the dryer Bisquick the fluffiness and moistness it needs. So, I recommend this, but I would HIGHLY recommend getting some Chebe too and cutting the Bisquick with it. Also, even though this mix has leavening agents in it, when we use recipes that call for leavening agents we add them anyway, it tends to turn out better this way.
Example Output: 4

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.
