Attempt at using roasted cocoa beans in the Keurig at work = epic fail and a huge mess.
Anyway, I had put the already ground cocoa beans in my grinder and made them finer which I was doing to make them in my drip pot. Apparently this helps to keep the water from flowing through, causing the top to pop off the reusable k-cup and water and grounds to overflow. I will try again tomorrow, leaving them in the coarser grind they come in. Wish me luck.
