I feel like Coffee grounds should be a type of spice that can be made with the Spice Mill, that way it'd be a little more convenient than having to find a grocery vendor to buy coffee. Then you could also make a variety of other beverages with it, like espresso or mocha cappucinos, something that could maybe give you a legit energy boost.
The only problem I can think of with this though is the process of actually making the coffee into a beverage. Not sure it'd work well in a frying pan or Saucepan, and I'd rather not have another piece of hardware like a Coffee/Hot Beverage maker to lug around as well, unless it could be placeable in a home.
Thoughts?
