Example Input: This is by far the best hot cocoa I have found yet for the Keurig. I love the assortment and the peppermint is my favorite. I would give these try for sure if you are looking for some hot cocoa K-cups. All the other selections for hot cocoa that I have tried were just okay tasting. These are AMAZING!!!! LOVE THEM! I will order these for sure again!
Example Output: 5

Example Input: With <a href="http://www.amazon.com/gp/product/B00389Q4XW">Green Mountain Hot Cocoa</a> being perpetually out of stock in the winter, I thought I'd give the cheaper Grove Square brand a shot.  Since the K-Cup patents are starting to sunset, Grove Square is one of the first "unofficial" producers of "we can't legally call these K-Cups but they work in your Keurig(R)(TM) coffee maker" pods, and I thought that I'd be getting the same overall quality, without the licensing fees tacked on to the price.  Well... I was right about Grove Square being cheaper. But I think that's the nicest I can be.  As others have pointed out, there's a definite "diet" or "<a href="http://www.amazon.com/gp/product/B000E6LBXK">Splenda</a>" aftertaste. This hadn't been reviewed yet when I bought it, so I didn't see the warnings from others, and re-checked the ingredients several times to make sure.  "Well... it's got 60 calories, which seems a bit lower than Green Mountain, but a bit high for something that diet-conscious people would want." and the ingredient list didn't seem to point to obvious "diet" sweeteners.  The overall taste is kind of like someone dropped a sugar-free Tootsie Roll in your hot water, using the normal cup setting. Going one size down didn't seem to improve much, beyond making a weak chocolate flavor sweeter - but that just meant a heavier shot of low-calorie sweetener to the taste buds.  The way I see it, I saved about $5 by going with this brand. On the other hand, now I've got 20 of these cups left that are probably going in the trash if I can't sucker someone... er... please my discerning guests... with a few cups.  If you drink diet soft drinks by choice, you're probably going to like this.

Example Input: Prior to ordering I misunderstood what truffle oil is... I warmly encourage potential buyers first to google "truffle oil"--you'll discover that there's no such thing. The "truffle essence" put in this and other truffle oils is a synthetic ingredient, whipped up in a lab, that mimics just one flavor of truffles. The aftertaste this (and any truffle oil) leaves is chemical. In order to make it work in a dish, you'll have cover it with garlic and other seasonings: basically, hide the flavor.  There are some oils available through Amazon in which actual truffles are infused, but the problem is that oil doesn't easily absorb real truffle essence, so the presence of authentic truffle flavor is very weak and nearly undetectable.  If you like this artificial flavor, then the price is right ($). But if you want real truffle flavor, get the real thing ($$$).
