It is potentially a total fluke that this worked at all, but it was so good I had to share! It seems that weirdly one of the essential ingredients may be a stolen 'tall' starbucks mug (it's the least we can do, tax-hogging gits), as this didn't work quite as well in a standard one when I made it again! It was damn beautiful the first time round any way.
70% cocoa chocolate (Green and Blacks) approx 8 chunks
Milk (enough for 2/3 of a mug)
Single cream (couple of tablespoons worth, but depends on you!)
Melt the chocolate in the microwave in a mug, being very careful not to burn it! Add milk a small amount at time, heat between each addition, mix well. Add a sprinkle of each of the spices, add the cream, heat a little more, stir well. I wish you luck!
