So, the verdict is that tere IS hope for this one. Mewakeling suggested I steep it for at least 20 minutes, so I left it in for 30, and it was still warm enough that my mug (colour-changing) hadn’t faded yet. Excellent!
It tasted a little ‘barky’ but still with a lot of chocolate. :D
I added a little milk to it too. Yep. This is much better. It’d almost make a hot chocolate substitute, if only I could get more chocolate in here. :P
