Just wanted to update on the two that I have tried since starting this thread...
I bought my husband one of those Keurig pod coffee machines and I tried the hot chocolate that came with it. Eh. It was ok, but not great.
I also bought "Winter" from Crate & Barrel and tried that for the first time yesterday. OMG, it was reallllly good. Like dangerously good. The only problem is that you use 3 tablespoons per 1/2 of water. That's like 4 sips of hot chocolate. And it's 160 calories for that little bit, so doubling it is ridiculous. But I drank it yesterday and love it. Oh the other bad thing is, it comes in this tin that seems big, but since you have to use 3 table spoons per serving, there are only 11 servings in the tin. Seems like not nearly enough for $15, or however much it was. Although, it's the best homebrew one I've had, so I'll probably be buying more!
