Example Input: I have been making Belgian waffles using the Stonewall Kitchen Farmhouse Pancake and Waffle Mix for over three years. My waffles are undoubtedly the best ever!!! I like my waffles light and crisp - I can't stand a heavy soggy waffle. These just melt in your mouth. I have made homemade waffles, but I have yet to find anything that can compare to this mix.
Example Output: 5

Example Input: I had high hopes for the convenience of this product. My daughter LOVES hot chocolate. This really was a total disappointment. I threw these kcups out. If you use the smallest setting on your Keurig, you get 3 oz of watery hot chocolate. Larger settings are not drinkable. Save your money and get cocoa packets or a good tin of hot cocoa - and take advantage of the instant hot water the keurig provides.

Example Input: I keep these on hand for car trips with the grandkids. You can turn a boring bottle of water into a flavorful Kool-Aid drink by just adding a single packet to it. Just open the bottle, pour in the contents of one packet, then close and shake. Each packet contains both the Kool-Aid mix and the amount of sugar that's needed for a single drink. Perfect size for a typical water bottle. We use reusable watter bottles with them, so we can fill them up with water when ever we need something to drink and then add the Kool-Aid. They taste just like when you mix a regular full sized pitcher of Kool-Aid, just in a single serving size. These single servings work really well for us since we never drink a whole pitcher when me make one, and end up pouring half of it out. These were such a great idea!
