Help me find this hot chocolate!

Hi, I'm hoping that someone out there will be able to help me once again find this hot chocolate that I bought probably some 10 years ago now. If memory serves me correct, I saw this written up in some magazine. It was ready made, came in a glass jar, and was solid at room temperature. When you heated it, it liquified and you were able to drink it. I assume that it probably had a high cocoa butter content.... thus the solidity at room temperature. Anyways, it was very expensive, and also the best hot chocolate I had ever had in my life. Rich beyond belief. Each jar was probably meant to be several servings, but of course I'm a fatty, so I finished each one off in one serving. I would LOVE to buy some more. Anybody know what I'm talking about??
