Input: Consider Input: Ew...I love Canada Dry and Schwepps, and I decided to try this brand because it was cheaper and it looked authentic. Not sure how the regular (non-diet) kind compares, but this tastes so diety--it's gross. I usually drink diet soda and don't mind the taste of diet coke, diet dr. pepper, diet sprite, (other diet gingerale, too) but this is REALLY GROSS. don't get it! You can definitely taste the ginger, but the overly saccharine taste ruins it.

Input: Consider Input: Ghirardelli isn't the finest chocolate you can buy, but it's pretty good, and the Intense Dark Assortment is both inexpensive, and provides you a few possibilities.  I've lately taken to unwrapping a 60%, 72% and 86% cacao square for each dinner guest and setting them on an individual saucer, to serve as an after-dinner sampler with red wine or Scotch. That's been a pretty popular approach. A similar approach also works "therapeutically"---if someone's having a bad day, sitting them down with a small assortment of increasingly intense chocolate isn't a bad path to feeling a little better.  I do wish that there were the same number of each in the bag; that's the only downside. Of course, if you really want the sets of three to serve to guests, you'll have to go through the tiresome task of somehow eating the extras. Darn.

Input: Consider Input: I am giving these two stars because they did taste sorta good at first.  But like the other reviewer said they do smell funny and they left a bad taste in my mouth.  And they are very salty.  I only cooked them for 90 seconds, the bag was still expanding when I stopped it but they smelled burnt when they were done (they said to cook until it stopped expanding but thank goodness I didn't do that).  Nice idea but I don't think I will buy these again.
