Ex Input:
I mainly use my Keurig for coffee but thought I'd try this one since I love dark chocolate and it was getting mostly good reviews.  I've tried some other chocolate K-cups and had given up on them since they all seemed pretty watery.  If I can taste water I don't consider it real hot chocolate.  I was pleasantly surprised that this tastes much better than the others I've tried.  (I must admit there are many I haven't tried, but I don't really feel like making a big scientific study of it.)  This will be my source of hot chocolate from now on.  I was a little disappointed to see how many ingredients it contains.  That sort of thing worries me a little.  Still, I don't drink hot chocolate that much, so I think I'll survive.  I'll copy the ingredient label here for those concerned plus a few items from the nutrition info:  Calories 60, from fat 20.  Trans Fat 0g. Sodium 200mg. Sugars 6g.  INGREDIENTS: sugar, glucose syrup solids, cocoa (processed with alkali), partially hydrogenated vegetable oil (may contain coconut, soybean, sunflower, palm and/or canola), modified whey, maltodextrin, salt, natural and artificial flavors, cellulose gum, sodium caseinate, cornstarch, lactose, dipotassium phosphate, sucralose, mono- and diglycerides, silicon dioxide, soy lecithin, artificial color. [Contains milk and soy.]  (I always hate seeing artificial coloring in "dark" chocolate products.)  If I had hot chocolate every day I would consider making it from scratch with more cocoa and fewer chemicals, but since I enjoy the convenience of having it nearly instantly from my Keurig on the occasional whim, I'll just keep a box of these K-cups on hand.  I highly recommend it for the taste, it isn't easy finding good hot chocolate.

Sooo good, I followed some advice and thought outside of the conventional box. Sliced up some cabbage and onion and sprinkled some Mae Ploy chili sauce on it with some Lime juice too, made a nice salad with a kick! also very good with cilantro and daikon.
